Question

A cyclist is riding up a hill having a constant slope of 30° with respect to the horizon at a constant speed (in a straight line). Which statement is true: A: The net force on the bike (due to gravity, the normal force, and friction) is in the direction of motion
B: The net force on the bike (due to gravity, the normal force, and friction) is zero
C: The net force on the bike (due to gravity, the normal force, and friction) is in the opposite direction of motion D: none of the statements above are true

Explanation / Answer

The net force on the bike (due to gravity, the normal force, and friction) is zero Since it moves with constant velocity.i.e., change in velocity is zero.So, accleration is zero. Therefore net force is zero
