A pendulum is raised to a certain height and released from point A, as shown in the image below. At its release, the pendulum is also given an initial
velocity of 14 m/s. Assuming that the effects of friction and air resistance
can be ignored, what will be the maximum height that the pendulum can
reach – that is, what is the height at point B? (Recall that g = 9.8 m/s2)
B
.
35 m
A. 25 m
B. 45 m
C. 20 m
D. 30 m

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
