I think the answer is A, please lmk if that is incorrect!
Answer
Given,
time = 8 s
θ = 17.5 rad
initial angular velocity = 0 rad/s
Using rotational motion equation

a. angular acceleration 
b. Average angular velocity = total angle/total time taken
=
= 2.187 rad/s
c. we have,
Angular velocity at end of 8 seconds
rad/s
d. we have, additional angle in next 8 seconds:
rads

Answer:
Law of conservation of mechanical energy.
Explanation:
During motion of a block sliding on the floor from the bottom of the ramp to the moment it stops , kinetic energy is converted into potential energy so that total energy remains constant . No other conversion is taking place , if we consider friction to be absent in the system . Potential energy and kinetic energy form part of mechanical energy . So we can say that mechanical energy is conserved . Hence , system is following law of conservation of mechanical energy.
