Question

D
A block of mass M is at rest on a ramp that is inclined at an angle 0 with respect to the horizontal. Frictional forces are
considered to be nonnegligible. The block is pushed against a spring and then held in place. The spring is compressed a distance
of x1, and the spring is not sec
after traveling a distance D, as shown above. Which of the following claims correctly describes the energy of the system under
consideration from when the block compressed the spring and when the block has traveled a distance D along the incline? Select
to the block. The block is then released from rest, travels up the incline, and comes to rest
two answers.
A
The mechanical energy of the system consisting of the spring increases by kx7.
The mechanical energy of the system consisting of the block does not change.
The mechanical energy of the system consisting of the block and Earth increases by more than zero but less
than ka?.
The mechanical energy of the system consisting of the spring, block, and Earth increases by kx?.

Expert Solution

Step 1

Two conditions are given. In one condition the spring is compressed by the block and in the second condition the block is being pushed away by a distance 'D'. Friction is nonnegligible. The two correct statements are needs to be identified
