Question

A car accelerates uniformly from rest at 2.2 m / s^2 for 3.0 s.
Calculate the speed of the car at time t = 3.0 s.

Answer 1

Answer:

6.6 m/s

Explanation:

u=0 (as car starts from rest)

a=2.2 m/s^2

t=3 seconds

we have to calculate v (speed)

so we can use 1st equation of motion

v=u+at

v=0+(2.2×3) m/s

v=6.6 m/s
