Can an object with constant acceleration reverse its direction of travel? Can it reverse its direction twice? In both cases, explain your reasoning.
An archer standing on the back of a pickup truck moving at 28m/s fires an arrow straight up at a duck flying directly overhead. The arrow was fired with an initial vertical velocity of 49 m/s relative to the truck.
a) for how long will the arrow be in the air?
b) how far will the aptruck travel while the arrow is in the air?
c) Where, in relation to the "duckless" archer, will the arrow come down? Will the archer have to 'duck'?
From the top of a cliff, a person throws a stone straight downward. The initial speed of the stone just after leaving the person's hand is 9.9 m/s.
(a) What is the acceleration (magnitude and direction) of the stone while it moves downward, after leaving the person's hand? Also, is the stone's speed increasing or decreasing?
(b) After 0.48 s, how far beneath the top of the cliff is the stone? (Give just the distance fallen, that is, a magnitude.)
