Question

A car accelerates from rest to 34 m/s in just 12 seconds. what is is acceleration?

Answer 1

Acceleration=(final velocity-initial velocity)/time
therefore
(34-0)/12
=2.83m/s

Answer 2

Hey!

u= 0 m/s
v=34m/s
t=12s
a=?

Using the first equation of motion,

v-u=at
34-0=a×12
34=12a
34/12=a
a=2.83 m/s^2


Hope it helps...!!!
