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

Question 1
Scenario #1:

140 meters
35 meters
280 meters
70 meters

Question 3
Scenario #2:
A pickup truck moving at 29 m/sec must come to a stop in a distance of 218 meters to avoid hitting a boulder that has fallen onto the road. How much time does the driver have to avoid an accident?
14.5 seconds
3.8 seconds
21.8 seconds
15.0 seconds

Question 5
Scenario #3:
A row boat, starting from rest, takes 7 seconds to travel 29 meters. If the boat maintains a uniform acceleration, what will be its instantaneous velocity at the end of this intial 7-second period?
2.65 m/sec
7.62 m/sec
8.29 m/sec
4.14 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 218 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?
29.8 seconds
38.6 seconds
19.2 seconds
22.8 seconds

Question 8
Scenario #4:
A go-cart, accelerating down a hill at 1.75 m/sec
2
can travel 48 meters in 7.25 seconds. What was the cart's initial velocity at the top of the hill after a subtle, not so official, push-start?
0.24 m/sec
0.22 m/sec
0.34 m/sec
0.91 m/sec

2.5 m/sec
6.6 m/sec
12.9 m/sec
9.3 m/sec
