1. Consider a metal loot...

1. Consider a metal loot crate, at the top of a frictionless ramp. If the mass of the loot crate is

12.8kg and the ramp has a rise of 3m and a run of 4m, then compute the following.

a) Compute the free body diagram of the loot crate a time 0. (i.e. when the loot crate is at

the top of the ramp.)

b) Compute the net force and the acceleration of the loot crate at time 0. Given the

frictionless surface what do we know about the acceleration as the object moves down

the ramp?

c) Consider the loot crate as it leaves the ramp and moves onto a at surface that now has

some friction. Compute the free body diagram for this situation. If coefficient of kinetic

friction is 0.42 (steel on steel), calculate the new net force and acceleration.

d) If we assume that the force of friction is constant after this point, how long will it take

for the loot crate to stop moving? At what distance in meters will the loot crate stop?

e) Include a short document (report) that includes a diagram that illustrates the problem

and your solution. Ensure you include appropriate labels and show your work
