Kinematics Equation 3

Question

An object accelerates from rest to 95 m/s over a distance of 43 m. What acceleration did it experience?

Answer 1

Given:

Initial Velocity: Vo = 0 (Rest)

Final Velocity: V = 95 m/s

Initial Distance: Xo = 0

Final Distance: X = 43 m

Find:

a = ?

Solution:

2 * a * (X - Xo) + Vo^2 = V^2

2*a*X = V^2

Ans:

a = V^2/(2*X) = 95^2/2*43 = 104.9 m/s^2
