Answer:

final velocity (v) = 72 km /h = 72 × 5/18 = 20 m/s. time (t) = 5 s. Acceleration (a) = v - u/t a = 20 - 15/ 5a = 5/5 a = 1 m/s^2. This discussion on A car is travelling at 54km/h.

Answer:

initial velocity = 54km/hr

= 54 × 1000/3600

= 15m/s

final velocity = 72km/h

= 72 × 1000/3600

= 20m/s

time taken = 5s

Acceleration = (v - u)/t

= (20-15)/5

= 5/5

= 1m/s^2
