You are given the following variables, calculate the work this object does!






t = 10 s
vi = 0 m/s
d = 100 m
θ = 0 degrees
m = 20 kg
vf = 15 m/s
The work you calculated is the Non-Conservative Work, solve for the height using the Conservation of
energy Equation.

1. Calculate the initial velocity of an object that traveled 30 m from rest.
2. What are all the Kinematic equations?
3. What Kinematic equation can you use to solve for time when all you have is displacement, initial
velocity, and acceleration?
4. Given Work, displacement, angle, mass how would you calculate acceleration?
