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

Question 1
Scenario #1:
A car accelerates uniformly from rest to a final speed of 23 m/sec in 8 seconds. How far does it travel during this period of acceleration?
184 meters
46 meters
92 meters
368 meters
omit
Question 2
What acceleration did the car is
Question 1
experience?
11.50 m/sec
^{2}
0.35 m/sec
^{2}
3.31 m/sec
^{2}
2.88 m/sec
^{2}
omit
Question 3
Scenario #2:
A pickup truck moving at 32 m/sec must come to a stop in a distance of 193 meters to avoid hitting a boulder that has fallen onto the road. How much time does the driver have to avoid an accident?
12.1 seconds
19.3 seconds
3.0 seconds
16.0 seconds
omit
Question 4
What acceleration did the truck experience in
Question 2
?
-6.03 m/sec

-2.65 m/sec
^{2}
-1.66 m/sec
^{2}
-8.00 m/sec

Question 5
Scenario #3:
A row boat, starting from rest, takes 8 seconds to travel 32 meters. If the boat maintains a uniform acceleration, what will be its instantaneous velocity at the end of this intial 8-second period?
8.00 m/sec
4.00 m/sec
2.83 m/sec
8.00 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 193 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?
41.6 seconds
28.1 seconds
20.1 seconds
19.6 seconds
omit
Question 7
What acceleration did the row boat initially experience in
Question 5
?
1.28 m/sec

0.50 m/sec
^{2}
1.00 m/sec
^{2}
0.28 m/sec
^{2}
omit
Question 8
Scenario #4:
A go-cart, accelerating down a hill at 2 m/sec
^{2}
can travel 66 meters in 8 seconds. What was the cart's initial velocity at the top of the hill after a subtle, not so official, push-start?
0.19 m/sec
0.25 m/sec
0.31 m/sec
1.03 m/sec
omit
Question 9
What was the cart's final velocity when it reached the bottom of the hill?
11.6 m/sec
2.8 m/sec
8.3 m/sec
16.2 m/sec
