The chemical potential energy in a given amount of gasoline is converted to kinetic energy in a car that increases its speed from 0 m/s to 32 m/s. To pass another car the driver accelerates to 64 m/s. Compare to the energy required to go from 0 to 32 m/s, the energy required to go from 32 m/s to 64 m/s is...

Help w/ Physics Homework?
A box of unknown mass is sliding with an initial speed
vi = 4.20 m/s
across a horizontal frictionless warehouse floor when it encounters a rough section of flooring
d = 2.10 m
long. The coefficient of kinetic friction between the rough section of flooring and the box is 0.100. Using energy considerations, determine the final speed of the box (in m/s) after sliding across the rough section of flooring.

Commercial airplanes are sometimes pushed out of the passenger loading area by a tractor.
a.) The 1800 kg tractor exerts a force of 1.55*10^4 N backward on the pavement, and the system experiences forces resisting motion that total 2400 N. If the acceleration is 0.190 m/s2, what is the mass of the airplane in kilograms?
b.) Calculate the force (in N) exerted by the tractor on the airplane, assuming 2100 N of the friction is experienced by the airplane.
