Acyclist pedals his bike and reaches the top of a hill. then he begins to coast downhill without pedaling. when he reaches the bottom of the hill, he again applies force to the pedals. why does the cyclist accelerate as he coasts downhill? a. the force of friction propels the cyclist and the bicycle down the hill. b. the mass of the cyclist opposes the mass of the bicycle, causing it to accelerate downhill. c. the unbalanced force of gravity acts on the mass of his body and the bicycle. d. the force of the cyclist and the force of the bicycle added together increase the downhill acceleration.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
