Please Answer the following problem 1 and 2. write clearly.
PROBLEM 1
A 5.96 − kg block is placed against a compress spring on a frictionless 27.0 degrees incline. The spring,
whose force constant is 2.5 N/cm, is compressed 21.3 cm, after which the block is released. How far up
the incline will the block go before coming to rest? Measure the final position of the block with respect
to its position just before being released. Consider two cases:
(a) the block is firmly attached to the spring, and
(b) the block is not attached to the spring and can loosely move up the incline
PROBLEM 2
During a rockslide, a 524 − kg rock slides from the rest down the hill slope that is 488 m long and
292 m high. The speed of the rock when it reaches the bottom of the hill is 62.6 m/s. How much
mechanical energy does the rock lose in the slide due to friction.
