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.)
A toy rocket is traveling to the right at 15.0 m/s when it undergoes a constant acceleration of 3.00 m/s2 to the left.
a) How long does it take before the rocket stops moving to the right?
b) What distance does the rocket travel before it stops moving to the right?
c) What distance does it travel in 7.00 s?
dog has an initial velocity v₁ = 2.6 m/s at the 55° direction
shown. If the dog's average acceleration is aa=0.85 m/s² pointed
straight to the right (also shown), what speed will the dog have
after 2.0 s?
(a) ₂ = 3.19 m/s
(b) 2 = 3.84 m/s
(c) ₂ = 4.3 m/s
(d) 24.98 m/s
(e) v₂ = 5.32 m/s
