Question

a car accelerates at the rate of 2m/s² for 10 seconds. if initial velocity is 2m/s find final velocity

Answer 1

given time equals to 10 seconds
acceleration equals to 2 metre per second square
initial velocity equals to 2 metre per second
V =u + a t
so v=2+2×10
that is V equals to 22 M per second

Answer 2

the acceleration is 2m/s^2
the time taken is 10 seconds
and the velocity is 2m/s.

according to the first equation of motion,
v=u+at
substituting the values given in the question we get
v=2+2×10
v=2+20
v=22
hence the final velocity is 22m/s.
