1. The problem statement, all variables and given/known data
2 crates, 75kg(crate x) and 110kg(crate z) are in contact and at rest on a horizontal surface. A 620N force is applied on crate x . If the coefficient of friction is 0.15, calculate:
a.) the acceleration of the system
b.)the force that each crate exerts on each other
c.) repeat when the crates reversed
2. Homework Equations
Msys = (massx)+(massz)
Force = mass(acceleration)
a. Msys = 75kg + 110kg
= 185kg
620N = 185kg(a)
a = 3.35m/s2
b.
cratex= 75kg(3.35m/s2)
=251.25N
cratez= 110(3.35m/s2)
=368.5N
c.
cratez= 110(3.35m/s2)
=368.5N
cratex= 75kg(3.35m/s2)
=251.25N
thanks in advance!
