m along the road to the top of the hill. If the
cyclist's initial speed is 8.90 m/s, what is the
final speed? Ignore friction and air resistance.

You throw a rock of mass 0.750 kg straight up in the air with an initial speed of 20.0 m/s. Throughout the flight of the rock assume there’s a constant air resistance force of magnitude 1.25 N acting on it. The trajectory of the rock is vertically up and down, with no horizontal motion.
(a) What is the maximum height reached by the rock?
(b) What is the speed of the rock when it returns to the point of release?
