Question

the speed of the car reduces from 15 m/s to 5 m/s over a displacement of 10 m​

Answer 1

Answer:

Here, initial velocity u=15m/s and final velocity v=5m/s

Using the formula, v2=u2+2aS ⇒52=152−2a(10) or a=−10m/s2 (negative sign indicates the car is deaccelerating)

Answer 2

the speed of the car reduces from 15 m/s to 5 m/s over a displacement of 10 m
