Suppose an object in free fall is dropped from a building. its starting velocity is 0 m/s. whats its speed (in m/s) of the object after falling 2 seconds?

A light spring has a force constant of 70 N/m and is used to pull a 10 kg box on a horizontal frictionless surface. If the box has an acceleration of 5 m/s2, by how much does the spring stretch if it pulls on the sled at 30.

A farmer uses a tractor to pull a 150 kg bale of hay up a 15∘ incline to the barn at a steady 5.0 km/h. The coefficient of kinetic friction between the bale and the ramp is 0.40. Part A What is the tractor's power output?

Identify the conditions for an elastic collision in a closed system. Check all that apply. Energy is conserved. Velocities may change. Momentum is conserved. Kinetic energy is conserved. Objects stick together after the elastic collision.

When the velocity of a mass on a spring is zero, the acceleration is at
