I'm doing my senior project on the negative effects of video games and I need an authentic experience. So far I have doing a big survey and interviewing a select group of kids that play a excess amount of video games. There are no facilities that house video game addicts so this has been very difficult for me. Creative and good ideas would help me greatly. thank you

A 5.5 kg ball is spun on a thin cord in a

vertical circle having 3.81 m radius. It has

a speed of 16.7 m/s at the highest point of

the circle. Take zero potential energy at the

lowest point and use the 69

◦

angle measured

with respect to the vertical as shown.

The acceleration of gravity is 9.8 m/s

What minimum speed v0 is required to keep

the ball moving in a circle?

Answer in units of m/s

This is my last problem and i don't know where to start help would be nice thank you.

You drag a suitcase of mass 7.2 kg with a

force of F at an angle 46.1

◦with respect to

the horizontal along a surface with kinetic

coefficient of friction 0.32.

The acceleration of gravity is 9.8 m/s

If the suitcase is moving with constant velocity 1.83 m/s, what is F?

Answer in units of N.

I thought the way to approach this was to set F*x=(1/2)*m*v^2

Given: g = 9.8 m/s2.

A small glass of water is placed on carousel

inside a microwave oven, at a radius 6.8 cm

from the center. The carousel rotates steadily,

tuning through one revolution every 9.4 s.

What angle does the water surface make

with the horizontal?

Answer in units of ◦

A 1.64 book in space has a weight of 6.96.

What is the value of gravitational field at

that location?

try not to gimme the answer but tell me which equations to use and give me the concept behind it.. please and thank you

I have a friend who is a really good goalkeeper. I asked him if he was going to college and he said he had no money and him and his parents are illegal. He is suprisingly smart(B and C student) Is there a way he can get a soccer schloarship and go to college, altough he is illegal

An airplane travels 180 m/s as it makes a

horizontal circular turn which has a(n) 2.2 km

radius.

What is the magnitude of the resultant

force on the 100 kg pilot of this airplane?

Answer in units of kN.

I dont know where to start

During a baseball game, a batter hits a popup to a fielder 73m away TIf the ball remains in the air for 6.9s high does the ball rise.. answer in meters. I found the horizontal velocity of 10.5 m/s but I do not know where to go from there
