A car moves at 13 m/s and coasts up a hill with a uniform acceleration of -1.6 m/s2.
(a) What is its displacement after 6.0 s?
(b) What is its displacement after 9.0 s?
Determine the displacement of a plane that experiences uniform acceleration from 58 m/s to 76 m/s in 12 s.
The driver of a car going 86.0 km/h suddenly sees the lights of a barrier 42.0 m ahead. It takes the driver 0.75 s to apply the brakes, and the average acceleration during braking is -10.0 m/s2.
(a) Determine whether the car hits the barrier.
(b) What is the maximum speed at which the car could be moving and not hit the barrier 42.0 m ahead? Assume that the acceleration doesn't change.
A golf ball rolls up a hill toward a miniature-golf hole. Assign the direction toward the hole as being positive.
(a) If the ball starts with a speed of 2.0 m/s and slows at a constant rate of 0.50 m/s2, what is its velocity after 2.0 s?
(b) If the constant acceleration continues for 6.0 s, what will be its velocity then?
(c) Describe in words and in a motion diagram the motion of the golf ball.
If a car accelerates from rest at a constant 4.5 m/s2, how long will it take for the car to reach a velocity of 29 m/s?
Good Luck
