Examples of Kinematics Problems

Kinematics SAT Physics exam questions involve operations with speed, velocity, acceleration; harmonic motion, rotational kinematics. Some of the SAT problems require knowledge of kinematics as well as other physics topics: dynamics, magnetism, etc.

1. A graduation hat is thrown vertically with a speed of 20m/s. How long does it take the hat to reach maximum height?
a) t = .2s
b) t = .5s
c) t = .8s
d) t = 1s
e) t = 2s

2. A soccer ball is kicked with an horizontal speed v = 10m/s from the height h = 20m, as shown in the figure below. Calculate the time passed from the moment the ball has an horizontal speed until the moment it touches the ground.

a) t = .2s
b) t = .5s
c) t = .8s
d) t = 1s
e) t = 2s

3. Calculate distance d from the problem above.
a) d = 10m
