Question

How long does it take to accelerate an object from rest to 12 m/s if the acceleration was 3 m/s2?

Answer 1

we know

v = u + (a×t)

Where

v is the final velocity

u is the initialvelocity

a is the acceleration

t is the time taken

So according to the question:-

12 = 0 + (3×t)

=> t = (12 ÷ 3) = 4

Therefore, the time required is 4 seconds..
