An object has a mass of 200kg initially moving along a horizontal surface with a velocity if 15ms is brought to rest by a force of 600N Caculate: (A) The deceleration (B) The horizontal distance travelled (C) The work done in bringing it to rest

Imagine the cart was dropped from rest from a height of 2.5m and allowed to free fall (assume air resistance is negligible). Compare the final speed achieved using (a) conservation of energy and (b) force and motion equations.

Using energy considerations, calculate the average force (in N) a 64.0 kg sprinter exerts backward on the track to accelerate from 2.00 to 5.50 m/s in a distance of 25.0 m, if he encounters a headwind that exerts an average force of 30.0 N against him.

A mass of 2.12 kg is initially at rest upon a frictionless incline with a 33.2 degree angle of inclination. If it is released fron rest, what will its speed be after sliding 1.70 m down the incline?
