Question

A car initially moving with a unifoum
Velocity of 36 km/h comes to a stop in
2s. find the retardation of the car
in Sl units.
​

Answer 1

90

Explanation:

as the unit is write and the é6 is known asthe lp

Answer 2

Answer:

5 m/s

Explanation:

u=36 km/h =10m/s

v=0 ( as it comes to rest )

t=2 s

using first equation of motion

v=u +at

0= 10 + 2a

-10 = 2a

-5 = a

as it was retardation so a comes negative
