Acar with a mass of 1.50 x 10^3 kg starts from rest and accelerates to a speed of 18.0 m/s in 12.0 s. assume that the force of resistance remains constant at 400.0 n during this time. what is the average power developed by the car's engine?

In what direction does an applied force move an object

Suppose a soccer ball is kicked from the ground at an angle 20.0º above the horizontal at 8.00 m/s. the y-velocity is determined to be 2.74 m/s. how long will the ball be in the air? assume the ball lands at the same height at which it was kicked.

Which best describes the difference between internal and thermal energy?
