Acceleration and Velocity Problems |

1) The head of a rattlesnake can accelerate at 50.0 m/s2 in
striking a victim. If a car could have the same acceleration, how long
would it take for it to reach a speed of 100.0 km/h from rest?

2) An airplane traveling southward is landing with a speed of 75
m/s. As it touches down, it has 800 m of runway to reduce its speed to
8.0 m/s. What is the acceleration of the plane as it slows down? (Make
sure to give the sign too)

3) A skier, starting from rest, accelerates down a slope at 2.2 m/s2.
How far has she gone after 5.0 s?

4) A soccer player, running at a speed of 3.2 m/s, decides to
accelerate. For the next 20.0 m, he speeds up with an acceleration of
0.50 m/s2. What is his speed at the end of the run?
