Question

A car starts from rest and after 10 seconds its velocity is 20 m/s. Find the acceleration and the distance travelled by it.​

Answer 1

a=
`2ms^(-2)` S=100m

Step-by-step explanation:

a=?

vi=0m/s

vf=20m/s

t=10s

a=
`(vf-vi)/(t)`

a=
`(20-0)/(10)`

a=2m
`s^(-2)`

S=?

S=vit+
`(1)/(2)`a
`t^(2)`

S=0+
`(1)/(2)`*2*
`(10)^(2)`

S=100m
