Directions:
On this worksheet you will practice solving problems by using the
five basic kinematics equations
for uniformly accelerated motion.

Question 1
Scenario #1:

352 meters
176 meters
88 meters
44 meters

Question 3
Scenario #2:
A pickup truck moving at 28 m/sec must come to a stop in a distance of 192 meters to avoid hitting a boulder that has fallen onto the road. How much time does the driver have to avoid an accident?
13.7 seconds
19.2 seconds
3.4 seconds
14.0 seconds

Question 5
Scenario #3:
A row boat, starting from rest, takes 8 seconds to travel 28 meters. If the boat maintains a uniform acceleration, what will be its instantaneous velocity at the end of this intial 8-second period?
7.48 m/sec
2.83 m/sec
3.50 m/sec
7.00 m/sec
omit
Question 6
At the point in the stream where the boat in
Question 5
is crossing, the stream is a total of 192 meters wide. If the boat continues maintaining the final velocity it achieves at the end of 8 seconds for the remainder of the trip, how much total time will it need to reach the opposite shore?
36.2 seconds
31.4 seconds
20.9 seconds
23.4 seconds

Question 8
Scenario #4:
A go-cart, accelerating down a hill at 2 m/sec
2
can travel 50 meters in 7 seconds. What was the cart's initial velocity at the top of the hill after a subtle, not so official, push-start?
1.02 m/sec
0.09 m/sec
0.19 m/sec
0.29 m/sec

7.1 m/sec
14.2 m/sec
10.1 m/sec
