Question

A car moves with initial velocity of 25m/s and reaches a velocity of 45m/s in 10s what is the acceleration of the car

Answer 1

Answer:

a=v-u/t

a= 45-25/10

a=20/10

a=2m/s^2

Answer 2

Acceleration =Change in velocity /Time taken Here, Change in velocity is nothing but Final velocity - Intial velocity

Final velocity =45m/s

Initial velocity = 25m/s

Time taken = 10s

so now Acceleration = 45-25/10

Acceleration = 20/10

Acceleration =2 (After simplifying with 5 table or by cancelling zeroes
