Question

a car accelerates from 18km/hr to 36km/hr in 5 seconds. calculate the acceleration and the distance covered by the car

Answer 1

acceration is change in velocity by time so 10-5/5=1m/s^2 is the acceleration.

Answer 2

Acceleration = [(final velocity - initial velocity)/time]

1 km/hr = (5/18) m/s

Therefore, 18 km/hr = [18*(5/18)] m/s

= 5 m/s.

And, 36 km/hr = [36*(5/18)] m/s

= 10 m/s

Therefore, acceleration = [(10 - 5)/5 sec]

Thus, acceleration = 1 m/s2.

i hope this helps you☺
