Question

body is at rest attains a velocity of 54 km/h in 10 sec. find the acceleration of the bo plase find the answer​

Answer 1

Explanation:

initial velocity=0 km/h=0m/s

final velocity=54 km/h=54×5/18=15 m/s

time=10s

acceleration=(v-u/t)

= 15-0/10

=3/2 m/s2

Answer 2

The Body is in Rest

Acceleration = v-u/t

Final Velocity = v = 54×5/18 = 15m/s

Initaial Velocity = 0m/s

Now Put the value in Formula

Acceleration = 15m/s - 0m/s/ 10s

= 15m/s/10

3/2m per second = 1.5m/s
