Question

A car starts frm rest and accelerates uniformly at 2 m s square fr 10sec what is the velocity at the end of 10 sec ?

Answer 1

Final velocity is `20` meters per second

Explanation:

The relation between initial velocity `u`, final velocity `v`, accelaration `a` and time `t` is given by

`v=u+at`

Here `u=0` `msec^(-1)` as car starts grom rest

`t=10` seconnds and `a=2` meter per square feet.

Hence `v=0+10xx2=20` meters per second.
