A bomb is dropped from an airplane at a height of 1200 meters. How long will it take to hit the ground?
If you drop an object from a specific height, it takes 0.84 seconds to hit the ground. If you throw a baseball horizontally with an initial speed of 22 m/s from the same height, how long will it take the baseball to hit the ground?
An object is dropped from rest of 35 m above the ground. A how long will it take for the object to hit the ground B What is th magnitude of the velocity just prior to hitting the ground
An object of mass 3kg is released from rest from a height h of 13 meters above the ground on a ramp. The object then slides down along a horizontal surface along a distance of d=20 meters where friction is present (\mu_s=0.5 and \mu_k=0.2), and compresses a horizontal spring initially unstretched until it finally comes to rest. If k=300N/m, by how much does the spring compresses (maximally) upon impact?
