what average force is required to atop an 1100 kg car in 8.0 s if the car is traveling at 72 mph?

determine the density of a 10.2 g sphere that has a radius of 5m.

if the height of the bannister was 5.68m, the time keepers reaction time was 0.2 s, and the time it took the ball to reach the ground was 1.25s. determine acceleration of gravity.

A 2290 kg car traveling at 11.7 m/s collides with a 2620 kg car that is initially at rest at the stoplight. The cars stick together and move 3.30 m before friction causes them to stop. Determine the coefficient of kinetic friction betwen the cars and the road, assuming that the negative acceleration is constant and that all wheels on both cars lock at the time of impact.

A spring with a mass of 2 kg has a damping constant 14 kg/s. A force of 3.6 N is required to keep the spring stretched 0.3 m beyond its natural length. The spring is stretched 0.7 m beyond its natural length and then released. Find the position of the mass at any time t. (Assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.) What is x(t)?
