Question

a car is travelling at a velocity of 72 km per hour in 10 seconds its velocity becomes 108 km per hour find the acceleration

Answer 1

Answer:

v=u+at

a=108 -72/10=30/10=3.6m/s^2

Answer 2

Answer:

the acceleration should be

acceleration = change in velocity / time taken

change in velocity = 36 km/h

and total time taken = 10 sec

so in meter per second

change in velocity = 10 m /s

acceleration = 1m/s
