8. A car starts from rest and 12.0 seconds later has traveled 81.0 meters as it accelerates.
A) What is the car’s rate of acceleration?
B) What is the car’s final velocity after 12 seconds?
9.
A plane is flying at +128 m/s as it is about to land. It can accelerate while braking at a maximum rate of
– 6.00 m/s2.
A) How long does it take the plane to reach a speed of 15.0 m/s?
B) How far down the runway does it achieve that speed?
10. A ball is dropped from a 14.0 meter high platform.
A) How fast will the ball be traveling as it hits the ground?
B) How long does it take the ball to reach the ground?
11. A stick is thrown straight up into the air. It takes 4.80 seconds to reach its highest point.
A) How fast was the stick thrown into the air?
B) How high up did it rise?
12. A ball is thrown into the air from a 9.00 meter tall platform with a velocity of +31.0 m/s.
A) How long is the ball in the air before it hits the ground below the platform?
B) How fast is the ball traveling as it strikes the ground?
13. What is the acceleration of an object that has reached its terminal velocity?
14. What determines an object’s terminal velocity?
