Answer 1

Answer #1

Answer:- 47.5 ft/s

Explanations:-

Here

H = 35.0 ft

g = 32.174 05 ft/s²

Using energy conservation here we will have,

Potential energy = kinetic energy

Mgh = 0.5 mv²

V = (2gh)^0.5 = 47.5 ft/s

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?
