Question

a car starts from rest and its velocity becomes 30m/s after 5 s calculate its acceleration

Answer 1

Answer:

a=(v-u)/t

a=(30)/5

a=6$ms^{-2}$

Answer 2

Explanation:

Initial velocity u = 0 m/s

Final velocity v = 30 m/s

Time taken = 5 sec

Acceleration = v-u/t

= (30 m/s-0m/s/5 sec)

= 30m/s/5s

= 6 m/s^2
