Answer 1

Answer #1

here,

the spring constant , K = 2 N/m

x = 2 cm = 0.02 m

using conservation of energy

initial potential energy of the block = potential energy stored in the spring

m * g * h = 0.5 * K * x^2

3 * 9.81 * h = 0.5 * 2 * 0.02^2

solving for h

h = 1.36 * 10^-5 m

the initial height of the block is 1.36 * 10^-5 m

An object of mass 3kg is released from rest from a height h of 13 meters...

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?
A block of mass m = 0.3kg, initially at rest, is dropped onto a massless spring...

A block of mass m = 0.3kg, initially at rest, is dropped onto a massless spring a distance h below. The block becomes attached to the spring and compresses it by (delta)x= 0.2 m before momentarily stopping. The spring constant k = 98 N/m. Air resistance is negligible. What is the initial height h of block above the top of the relaxed spring?

In the figure, a block of mass m = 11 kg is released from rest on a frictionless incline of angle θ = 26°. Below the block is a spring that can be compressed 3.4 cm by a force of 320 N. The block momentarily stops when it compresses the spring by 5.3 cm. (a) How far does the block move down the incline from its rest position to this stopping point? (b) What is the speed of the block...

d = the distance the spring compresses A block of mass M is placed on an...

d = the distance the spring compresses A block of mass M is placed on an inclined plane that makes an angle theta relative to the horizontal. The block and plane interact with friction coefficients. The angle of inclination is greater then that required for the block to slip and so once it is released, the mass begins to move. It slides a distance L until it makes contact with a spring with stiffness k. The spring compresses a distance...

A 10kg block is released from rest at a height of 5m off of the ground. A 1m long spring sits directly below it to catch it.
