(a)
if the coconut weighs 1.5kg, and it is falling at 2m/s,
what is its momentum?

b)
at first the coconut speeds up as it falls. explain why in
terms of the forces acting on it.

(c)
explain what happens to the speed of the coconut
eventually (before it hits the ground) if the tree is very
tall.

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s. assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
