Question

The speed of a car as a function of time is shown in the figure above. Find the distance travelled by the car in 8 seconds and its acceleration.​

Answer 1

Answer:

speed = distance / time

therefore , 20 = distance / 8

distance = 20/8 = 2.5 m

by definition , v = u + at

therefore , 20 = 0 + a× 8

a= 20/8 = 2.5 m/s
