Question

An object experiences an acceleration of -6.8 m/s. as a result it accelerates from 54 m to a complete stop. How much distance did it travel ?

Answer 1

Let's put out the known variables first

Answer 2

We know that:
Acceleration = -6.8 m/s²
V1 = 54 m
V2 = 0
D = ?

Answer 3

You should be able to solve for Distance after rearranging the equationa bit

Answer 4

V2² = V1² + 2ad
V2² - V1² / 2a = d
0 - 54² / 2(-6.8) = d ?
