A truck covers 40.0 m in 8.40 s while uniformly slowing down to a final velocity of 1.20 m/s. (a) Find the truck's original speed. (b) Find its acceleration.

A spaceship starts at rest, and then launches vertically into the air with an upward acceleration of 2.0 m/s2. When it reaches a height of 500 m, it runs out of fuel; after this point its acceleration is due to gravity, i.e. 9.8 m/s2 downward. (ignore air resistance)(a) How long does it take the spaceship to run out of fuel? (b) What is its velocity at the point when it runs out of fuel? (c) What is the maximum height that the spaceship reaches? (d) For how much time (total, from launch) is the rocket in the air? (e) What is the spaceship’s velocity just before it hits the ground?

A scooter has a constant acceleration of +4.0 /s. Find its displacement after 2.0 s, if the initial velocity of the boat is +8.0 m/s. a) 42 m; b) 28 m; c) 24 m; d) 14 m.

A jogger accelerates from rest to 3.12 m/s in 3.52 s. A car accelerate from 22.2 to 39.7 m/s also in 3.52 s. (a) Find the magnitude of the acceleration of the jogger. (b) Determine the magnitude of the acceleration of the car. (c) How much futher does the car travel than the jogger during the 3.52 s?
