Linear motion and equations of motion

Question 1 of 10

A car accelerates uniformly from 10 m/s to 40 m/s in 4 s. Its acceleration is ___ m/s².

Question 2 of 10

A car starts with velocity 0 m/s and accelerates at 3 m/s² for 10 s. Find its final velocity.

Question 3 of 10

A car starts from rest and accelerates uniformly to 30 m/s in 5 s. It travels at this speed for 20 s, then decelerates uniformly to rest in 5 s. (a) Sketch the velocity–time graph. (b) Find the acceleration and the deceleration. (c) Find the total distance travelled. (d) Find the average speed for the journey.

Question 4 of 10

A car accelerates uniformly from 10 m/s to 30 m/s in 2 s. Its acceleration is ___ m/s².

Question 5 of 10
