On my laptop my internet connection is significantly slower than other people who use the very same internet connection that I do in my dorm room have much faster speeds. My laptop isn't even a year old and people with older laptops do not have the same issues. I have cleared my browsing history to try and speed things up but that isn't helping either. My internet is just slower than most people who use the same internet access point as me in my dorm, in classrooms, and in other people's dorms. Why would that be? Any suggestions on how I can improve my internet?

What are the advantages and disadvantages?

How would we figure this out?

Two window washers, Bob and Joe, are on a 3.00 m long, 380 N scaffold supported by two cables attached to its ends. Bob weighs 765 N and stands 1.00 m from the left end, as shown in the figure below. Two meters from the left end is the 500 N washing equipment. Joe is 0.500 m from the right end and weighs 880 N. Given that the scaffold is in rotational and translational equilibrium, what are the forces on each cable?

A skier starts from rest at the top of a hill that is inclined at 10.5° with the horizontal. The hillside is 215 m long, and the coefficient of friction between snow and skis is 0.0750. At the bottom of the hill, the snow is level and the coefficient of friction is unchanged. How far does the skier glide along the horizontal portion of the snow before coming to rest?

A railroad car of mass 3.5 x 10^4 kg moving at 2.00 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.20 m/s.

(a) What is the speed of the three coupled cars after the collision?

(b) How much kinetic energy is lost in the collision?

Identical twins, each with mass 56.9 kg, are on ice skates and at rest on a frozen lake, which may be taken as frictionless. Twin A is carrying a backpack of mass 12.0 kg. She throws it horizontally at 3.20 m/s to Twin B. Neglecting any gravity effects, what are the subsequent speeds of Twin A and Twin B?

Twin A =

Twin B =

I have a problem where the answer is 19992 J and the next part of the question says... What is this in horsepower? How do I solve that? Thanks.

A 44 kg pole vaulter running at 12 m/s vaults over the bar. Her speed when she is above the bar is 0.7 m/s. Neglect air resistance, as well as any energy absorbed by the pole, and determine her altitude as she crosses the bar.

All I need is an equation to help solve this problem.

A dockworker loading crates on a ship finds that a 23 kg crate, initially at rest on a horizontal surface, requires a 70 N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 60 N is required to keep it moving with a constant speed. Find the coefficients of static and kinetic friction between crate and floor.

I don't know what to do PLEASE help!!

A novice golfer on the green takes three strokes to sink the ball. The successive displacements are 4.00 m to the north, 2.10 m northeast, and 1.00 m at 35.0° west of south. Starting at the same initial point, an expert golfer could make the hole in what single displacement?

answers are in metres and degrees NE

An object with mass m1 = 4.00 kg, rests on a frictionless horizontal table and is connected to a cable that passes over a pulley and is then fastened to a hanging object with mass m2 = 10.0 kg, as shown in the figure below. Find the acceleration of each object and the tension in the cable.

A) mass m1

B) mass m2

C) tension

A shopper in a supermarket pushes a loaded cart with a horizontal force of 11 N. The cart has a mass of 30 kg.

(a) How far will it move in 10.0 s, starting from rest? (Ignore friction.)

(b) How far will it move in 10.0 s if the shopper places his 30 N child in the cart before he begins to push it?

I think I have A correct but I am not sure about B

After falling from rest from a height of 27 m, a 0.49 kg ball rebounds upward, reaching a height of 17 m. If the contact between ball and ground lasted 1.6 ms, what average force was exerted on the ball?

A 5.2 g bullet leaves the muzzle of a rifle with a speed of 318 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.75 m long barrel of the rifle?

Show work I am confused

The air exerts a forward force of 15 N on the propeller of a 0.10 kg model airplane. If the plane accelerates forward at 3.0 m/s2, what is the magnitude of the resistive force exerted by the air on the airplane?

A freight train has a mass of 1.1 multiplied by 107 kg. If the locomotive can exert a constant pull of 7.8 multiplied by 105 N, how long does it take to increase the speed of the train from rest to 60 km/h?

the answer should be in minutes
