A cyclist, whilst overtaking another bike, increases his speed uniformly from 4.2 m s–1 to 6.3 m s–1 over a time interval of 5.3 s. Determine the acceleration and distance travelled.

A car starts from rest at t = 0 s, and speeds up with a constant acceleration of 1.81 m/s2 for 6.00 s. Then it continues with a uniform speed for another 6.00 s. Finally, it speeds up with a constant acceleration of 2.02 m/s2 until it reaches a speed of 18.0 m/s. (a) How long does it take for the car to reach a speed of 18.0 m/s? Time is measured from the beginning at t = 0  (b) What is the total displacement of the car?

A motorist traveling at a constant speed of 10.0 m/s. A police officer behind him 30.0 m starts in pursuit with a constant acceleration 2.00 m/s2, how much time elapses before the officer passes the motorist?

A person walks first at a constant speed of 4.90 m/s along a straight line from point to point and then back along the line from to m/s. (a) What is her average speed over the entire trip? m/s (b) What is her average velocity over the entire trip? m/s @ at a constant speed of 3.10
