Question

A car moving with an initial velocity of 30 m/s accelerates at the rate of 6 m/s2 for
10 s.Calculate its final velocity.

Answer 1

Initial velocity = u = 30m/s

Final velocity = v = ?

acceleration = a = 6m/s2

time = t = 10s

According to first equation of motion

V = U + at

V = 30 + 6*10

v = 30 + 60

Final velocity = V = 90 m/s

Answer 2

Answer:

90m/s

Explanation:

u=30m/s

a=6m/s2

t=10s

v=?

a=v-u/t

=6=v-30/10

=60=v-30

=90m/s=v
