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

121 meters
61 meters
242 meters
484 meters

Question 3
Scenario #2:
A pickup truck moving at 33 m/sec must come to a stop in a distance of 185 meters to avoid hitting a boulder that has fallen onto the road. How much time does the driver have to avoid an accident?
18.5 seconds
11.2 seconds
2.8 seconds
16.5 seconds

Question 5
Scenario #3:
A row boat, starting from rest, takes 11 seconds to travel 33 meters. If the boat maintains a uniform acceleration, what will be its instantaneous velocity at the end of this intial 11-second period?
6.00 m/sec
3.00 m/sec
3.32 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 185 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?
25.3 seconds
26.0 seconds
40.3 seconds
36.3 seconds

Question 8
Scenario #4:
A go-cart, accelerating down a hill at 2.75 m/sec
2
can travel 95 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?
0.16 m/sec
1.40 m/sec
0.33 m/sec
0.19 m/sec

Question 9
What was the cart's final velocity when it reached the bottom of the hill?
16.2 m/sec
11.5 m/sec
3.4 m/sec
22.9 m/sec
