Question

Whats the answer for this question ?

A block of mass m = 3.10 kg is released from rest at a height of H = 7.00 m on a curved frictionless ramp. At the foot of the ramp is a spring whose spring constant is k = 484.00 N/m. What is the maximum compression of the spring, x? Answer: A small block of mass m = 1.6 kg slides, without friction, along the loop- the-loop track shown, the block starts from the point P at rest a distance h = 57.0 m above the bottom of the loop of radius R = 20.0 m. What is the kinetic energy of the mass at the point A on the loop?

Explanation / Answer

a block of mass is released from frictionless ramp

at a height of 7m

according to law of conservation of energy

KI+UI=KF+UF

KI=KF=0

UI=UF

mgh=0.5kx2

3.1*9.8*7=0.5*484*x2

x=0.93m
