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 22 m/sec in 8 seconds. How far does it travel during this period of acceleration?
88 meters
44 meters
352 meters
176 meters
omit
Question 2
What acceleration did the car is
Question 1
experience?
11.00 m/sec
^{2}
3.03 m/sec
^{2}
0.36 m/sec
^{2}
2.75 m/sec
^{2}
omit
Question 3
Scenario #2:
A pickup truck moving at 34 m/sec must come to a stop in a distance of 180 meters to avoid hitting a boulder that has fallen onto the road. How much time does the driver have to avoid an accident?
10.6 seconds
2.6 seconds
17.0 seconds
18.0 seconds
omit
Question 4
What acceleration did the truck experience in
Question 2
?

^{2}
-3.21 m/sec
^{2}
-8.50 m/sec
^{2}
-1.89 m/sec

Question 5
Scenario #3:
A row boat, starting from rest, takes 8 seconds to travel 34 meters. If the boat maintains a uniform acceleration, what will be its instantaneous velocity at the end of this intial 8-second period?
2.83 m/sec
8.25 m/sec
4.25 m/sec
8.50 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 180 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?
18.4 seconds
17.2 seconds
25.2 seconds
44.5 seconds
omit
Question 7
What acceleration did the row boat initially experience in
Question 5
?
0.33 m/sec

1.34 m/sec
^{2}
0.53 m/sec
^{2}
1.06 m/sec
^{2}
omit
Question 8
Scenario #4:
A go-cart, accelerating down a hill at 2 m/sec
^{2}
can travel 74 meters in 8.5 seconds. What was the cart's initial velocity at the top of the hill after a subtle, not so official, push-start?
0.18 m/sec
0.24 m/sec
0.23 m/sec
1.02 m/sec
omit
Question 9
What was the cart's final velocity when it reached the bottom of the hill?
2.9 m/sec
8.7 m/sec
12.2 m/sec
17.2 m/sec
