Question

Physics
Scooter aquires a velocity 18 km/hs in 4 seconds
just after the start .Find its acceleration.


​

Answer 1

Answer:

acceleration = velocity/time

here,

velocity= 18km/h

=[ 18 × (5/18) ] m/s

= 5m/s

now, acceleration =( 5/4) m/s^2 [since time taken to acquire the velocity is =4 seconds]

Answer 2

Explanation:

v=36 km/hr

v=36×

18

5

=10 m/s

u=0

t=10 sec

v=u+at

10=0+a(10)

10=10a

a=1 m/s
