Question

While driving, the man observes a cloud of vehicles ahead and reduces his speed. Find the
acceleration of the vehicle if the speed changes from 78 km h-1
to 60 km h-1
in 10 second.

Answer 1

Answer:

Here is your answer

Explanation:

Initial velocity = 78 km/h = 21.67 m/s

Final velocity = 60 km/h = 16.66 m/s

Acceleration = v-u/t = 16.66 - 21.67/ 10 = -5.01/10 = 0.501 m/s
