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 18 m/sec in 11 seconds. How far does it travel during this period of acceleration?
99 meters
50 meters
396 meters
198 meters

Question 2
What acceleration did the car is

experience?
1.47 m/sec
^{2}
9.00 m/sec
^{2}
1.64 m/sec
^{2}
0.61 m/sec
^{2}
omit
Question 3
Scenario #2:
A pickup truck moving at 30 m/sec must come to a stop in a distance of 221 meters to avoid hitting a boulder that has fallen onto the road. How much time does the driver have to avoid an accident?
22.1 seconds
3.7 seconds
14.7 seconds
15.0 seconds
omit
Question 4
What acceleration did the truck experience in

Question 5
Scenario #3:
A row boat, starting from rest, takes 11 seconds to travel 30 meters. If the boat maintains a uniform acceleration, what will be its instantaneous velocity at the end of this intial 11-second period?
5.45 m/sec
7.75 m/sec
2.73 m/sec
3.32 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 221 meters wide. If the boat continues maintaining the final velocity it achieves at the end of 11 seconds for the remainder of the trip, how much total time will it need to reach the opposite shore?
36.3 seconds
46.0 seconds
29.9 seconds
35.0 seconds

Question 7
What acceleration did the row boat initially experience in

^{2}
0.17 m/sec
^{2}
0.25 m/sec
^{2}

Question 8
Scenario #4:
A go-cart, accelerating down a hill at 2.75 m/sec
^{2}
can travel 79 meters in 7.5 seconds. What was the cart's initial velocity at the top of the hill after a subtle, not so official, push-start?
0.37 m/sec
0.22 m/sec
0.22 m/sec
1.40 m/sec
omit
Question 9
What was the cart's final velocity when it reached the bottom of the hill?
3.2 m/sec
20.8 m/sec
14.8 m/sec
10.5 m/sec
