Question

Q. If a car has a constant acceleration of 4 m/s2, starting from rest, how fast is it travelling after 5 seconds?

Answer 1

Answer: 10m/s

Explanation: Initial velocity(u) of the car = 0(starts from rest)

Time taken(t) = 5 sec

We have to find the final velocity(v)

v = u +at

v = 0 + 2(5)

v = 10

Therefore final velocity of the car is 10m/s

So it travels at 10m/s after 5 seconds
