how long would it take for an object dropped from the leaning tower of pisa (height 54.6 meters) to hit the ground
An object is dropped from rest from three different heights a) 1m b)1.2m c)1.5m Calculate the speed of the object using all three heights just before it hits the ground. Then derive the speed of the object as a function of height dropped. Please give proper reasoning and details. I will give thumbs up.
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?
Two identical objects are dropped from rest at the same time. Object A is dropped from twice the height of object B. If there is no air resistance, which statement is true? None of the answers given is true. Both objects hit the ground at the same time. Object A takes twice the time to fall as object B. Object A takes four times the time to fall as object B.
