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

Question 1
Scenario #1:

58 meters
230 meters
115 meters
460 meters
omit
Question 2
What acceleration did the car is
Question 1
experience?
2.65 m/sec
^{2}
0.43 m/sec
^{2}
2.30 m/sec
^{2}
11.50 m/sec
^{2}
omit
Question 3
Scenario #2:
A pickup truck moving at 33 m/sec must come to a stop in a distance of 186 meters to avoid hitting a boulder that has fallen onto the road. How much time does the driver have to avoid an accident?
16.5 seconds
18.6 seconds
11.3 seconds
2.8 seconds
omit
Question 4
What acceleration did the truck experience in

Question 5
Scenario #3:
A row boat, starting from rest, takes 10 seconds to travel 33 meters. If the boat maintains a uniform acceleration, what will be its instantaneous velocity at the end of this intial 10-second period?
6.60 m/sec
3.30 m/sec
3.16 m/sec
8.12 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 186 meters wide. If the boat continues maintaining the final velocity it achieves at the end of 10 seconds for the remainder of the trip, how much total time will it need to reach the opposite shore?
33.2 seconds
23.7 seconds
23.2 seconds
41.0 seconds

Question 7
What acceleration did the row boat initially experience in

0.24 m/sec
^{2}
0.33 m/sec
^{2}
0.66 m/sec

Question 8
Scenario #4:
A go-cart, accelerating down a hill at 2.5 m/sec
^{2}
can travel 87 meters in 8.25 seconds. What was the cart's initial velocity at the top of the hill after a subtle, not so official, push-start?
0.28 m/sec
1.28 m/sec
0.30 m/sec
0.19 m/sec
omit
Question 9
What was the cart's final velocity when it reached the bottom of the hill?
20.8 m/sec
10.5 m/sec
3.2 m/sec
14.8 m/sec
