Question

A.Your mass m=11 kg block slides down a frictionless ramp having angle theta=0.51 radians to the horizontal. After sliding down the ramp a distance L=16 m the block encounters a spring of spring constant k=551 N/m. The spring is parallel to the ramp. Use g=9.74 m/s/s for the acceleration of gravity.

Calculate the maximum compression of the spring, in meters. Include labeled diagrams showing the initial and final configurations, and a discussion of the solution method based on energy conservation.

B. Your mass m=9 kg block slides on a frictionless horizontal
surface with initial velocity v_{0}=26 m/s until it
encounters a patch of the surface having friction coefficient mu(x)
=c x^{n} where n=4, c=2.32 m^{-n}, and x is the
distance into the patch. Use g=9.72 m/s/s.

Calculate the distance into the patch where the block stops, in meters, assuming the patch has sufficient length to stop the block. draw a clearly labeled diagram

A 0.62 kg car slides 0.24 m down a frictionless ramp at an angle
of 30 degrees. It travels across a frictionless surface and into a
spring with k = 55 N/m.
Determine the maximum acceleration of the toy car after it hits
the spring.

A block (4 kg) starts from rest and slides down
a frictionless ramp #1 of height 9 m. The block
then slides a horizontal distance of 1 m on a
rough surface with kinetic coefficient of friction

another frictionless ramp #2.

traveling across the rough surface: K...

An 8.70-kg block slides with an initial speed of 1.80 m/s down a
ramp inclined at an angle of 25.3 ∘ with the horizontal. The
coefficient of kinetic friction between the block and the ramp is
0.87. Use energy conservation to find the distance the block slides
before coming to rest.

A 1.55-kg block is launched by a spring and slides along a ramp
as shown. The spring has a spring constant of 1180 N/m and is
compressed a distance, x, before being released. The block slides
up a frictionless ramp of height, H=0.550 m, above where the block
leaves the spring. At the top of the ramp it flies horizontally off
the ramp. Just before leaving the ramp, the kinetic energy of the
block is 8.54 J. After leaving the...

A 0.20-kg block slides from rest down a frictionless track from
a height of 1.5 m, and encounters a loop that is 1.0 m high. (a)

block is slowed by a spring at the bottom of the track. If the
stiffness of the spring is 0.90 kN/m, how far does the block slide

The horizontal surface on which the block slides is
frictionless. The speed vi of the block of mass m= 2.0 kg before it
touches the spring is 10 m/s. After the spring is compressed by
0.20 m, the block starts to move back to the right. What is the
velocity vf of the block in m/s when the spring is compressed by
0.15m ?

A block of mass m = 0.53 kg attached to a spring with force
constant 119 N/m is free to move on a frictionless, horizontal
surface as in the figure below. The block is released from rest
after the spring is stretched a distance A = 0.13 m. (Indicate the
direction with the sign of your answer. Assume that the positive
direction is to the right.)
