Question

5.
If a scooter acquires a velocity of 36 kmph in 10 s just after its start, then the acceleration of the sco
IC
a) 3 ms^-2
b) 2 ms^-2
c) l ms^ -2
d) 0.5 ms ^-2
​

Answer 1

Answer:

At first we will change 36kmph in mps

so, 36×1000/60×60=10 m/s

a= v/t

= 10/10

=1 m/s²

mark me as brainliest

Answer 2

Answer:

1ms^-2

Given initial velocity =36kmph and time =10s

So first of all change kmph into m/s because acceleration is always in m/s. So 36*5/18=10m/s.

So initial velocity will be 10 m/s.

Acceleration = final velocity - initial velocity /time.

So acceleration =10-0/10=1m/s^2 answer
