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 24 m/sec in 7 seconds. How far does it travel during this period of acceleration?
168 meters
84 meters
336 meters
42 meters
omit
Question 2
What acceleration did the car is
Question 1
experience?
4.11 m/sec
^{2}
3.43 m/sec
^{2}
12.00 m/sec
^{2}
0.29 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 214 meters to avoid hitting a boulder that has fallen onto the road. How much time does the driver have to avoid an accident?
3.1 seconds
17.0 seconds
12.6 seconds
21.4 seconds
omit
Question 4
What acceleration did the truck experience in
Question 2
?

^{2}
-8.50 m/sec
^{2}
-6.29 m/sec

Question 5
Scenario #3:
A row boat, starting from rest, takes 7 seconds to travel 34 meters. If the boat maintains a uniform acceleration, what will be its instantaneous velocity at the end of this intial 7-second period?
4.86 m/sec
8.25 m/sec
9.71 m/sec
2.65 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 214 meters wide. If the boat continues maintaining the final velocity it achieves at the end of 7 seconds for the remainder of the trip, how much total time will it need to reach the opposite shore?
17.6 seconds
45.5 seconds
25.5 seconds
18.5 seconds
omit
Question 7
What acceleration did the row boat initially experience in
Question 5
?

0.32 m/sec
^{2}
1.38 m/sec
^{2}
1.39 m/sec
^{2}
omit
Question 8
Scenario #4:
A go-cart, accelerating down a hill at 1.75 m/sec
^{2}
can travel 65 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?
0.21 m/sec
0.90 m/sec
0.21 m/sec
0.21 m/sec
omit
Question 9
What was the cart's final velocity when it reached the bottom of the hill?
7.6 m/sec
15.1 m/sec
10.8 m/sec
2.7 m/sec
