Question

a car is moving with a speed of 54 km/hr. It stopped in 10 seconds after applying brakes . Calculate the acceleration of the car​

Answer 1

Answer:

-3/2

Explanation:

u = 54 km/hr = 54 x 5/18 = 15m/s

v = 0 m/s (as itcomes to rest finally)

t = 10s

a = ?

v = u + at

0 = 15 + a(10)

a = - 15/10

a = - 3/2

so it is the final amswer
