Question

Deceleration equals 2.45m/s^2, distance equals 15m where at this distance the velocity is 0m/s, what is the velocity at distance equals 0m?

Answer 1

Do you have the time of any of these places?

Answer 2

let x = time (s)
So far we have f"(x) = -2.45
f'(x) = -2.45x + c
We need both f'(x) and x to find c.

Answer 3

You do not know the time

Answer 4

Velocity = distance/time
Distance is zero, so velocity must also be zero?

Answer 5

You are trying to find the velocity when the displacement is 0m

Answer 6

Oh, you're right.
