Question

a vechile start from a rest and attains a velocity of 72 km per hrs 10 sec calculate the accelaration of the vechile​

Answer 1

Answer:

a= 7.2 m/s^2

Explanation:

V - U = at

v= 72 km/hr = 72×5/18 = 20 m/sec

u= 0 m/s

t = 10 sec

v - u = at

a = v-u/t

  = 72 - 0/ 10

 = 72/10

 = 7.2 m/s^2
