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. Upon landing, the block compresses the spring to
0.5m, where it comes to rest (but only for an instant!).
a)
At some point the block has a maximum velocity.
Describe when it is (using words).
b)
What is the spring constant?
c)
How much has the spring squished when the speed is maximum?
d)
What is the maximum speed?

A block of mass 10kg is released from rest and slides down a frictionless track of height h 5m above a table (see figure). At the bottom of the track, where the surface is horizontal, the block strikes and sticks to a light spring with spring constant k 10k the acceleration of gravity to be 9.81 The maximum distance d the spring is compressed is
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 small block of mass m1 is released from rest at the top of a curve-shaped, frictionless wedge which sits on a frictionless horizontal surface as shown. The height of the wedge is h = 5 m. When the block leaves the wedge its velocity relative to the ground is measured to be 4.00 m/s to the right as shown in the figure. If the mass of the block is doubled to become 2m1, what will be its speed when...
4. (15 pts) A small block with a mass 'm', is released from rest at an initial height 'h'. the mass slides down a ramp and then through a 'dip' with a given radius of curvature '. at the lowest point of the curve, the mass as a velocity of vc (velocity at curve). The mass continues back up and eventually slides over a friction patch of length 'd' when it eventually reaches an uncompressed spring. The mass compresses the...
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...
A 700 g block is released from rest at height ho above a vertical spring with spring constant k = 405 N/m and negligible mass. The block sticks to the spring and momentarily stops after compressing the spring 17.5 cm. (a) How much work is done by the block on the spring? (b) How much work is done by the spring on the block? (c) What is the value of ho? (d) If the block were released from height 2.00ho...
A 943 g block is released from rest at height ho above a vertical spring with spring constant k = 540 N/m and negligible mass. The block sticks to the spring and momentarily stops after compressing the spring 24.5 cm. How much work is done (a) by the block on the spring and (b) by the spring on the block? (c) What is the value of ho? (d) If the block were released from height 4ho above the spring, what...
A small block of mass m, is released from rest at the top of a curve-shaped, frictionless wedge which sits on a frictionless horizontal surface as shown. The height of the wedge is h = 5 m.
