Question

A car initially at rest accellerates in a straight line at 6 m/s2. what will be its speed after 3 seconds?

Answer 1

Answer:

18 m per sec

Explanation:

we have V = U + At ; V= final-velocity U = initial-velocity A =acceleration and t is time

so as starting fro the rest so U is zero

so ;

V = 0 + 6 x 3

   = 18

so the speed is 18 meter per second
