Question

Give the NUMERICAL value to the following question. If a car was traveling 25

m/s and then accelerated at a rate of 5 m/s/s for 3 s, then what was the final
velocity?

Answer 1

Given,

initial velocity= 25m/s

acceleration= 5 m/s

time= 3 s

final velocity= ?

We know that,

acceleration= final velocity- initial velocity/ time

or, 5 = final velocity- 25 / 3

or, 5*3 = final velocity- 25

or, 15+ 25= final velocity

Therefore, final velocity is 40 m/s.
