Question
Sisyphus is pushing a huge boulder up a hill at a constant velocity. What can you say about the net force on the boulder?
a) The net force on the boulder is equal to the force of push applied by Sisyphus
b) The net force on the boulder has equal magnitude but opposite direction to the force of push applied by Sisyphus
c) There is not enough information provided to determine the net force on the boulder
d) The net force on the boulder is equal to mass of the boulder times its velocity
e) The net force on the boulder is zero
Explanation / Answer
According to newton second law of motion
F=ma
if net force on body is zero from above equation a=0 or body moves with constant velocity.
so option
b) The net force on the boulder has equal magnitude but opposite direction to the force of push applied by Sisyphus
is correct.
