We want to lower crate m1 down the ramp shown below with an acceleration of 1.25m/s².There is no friction on the ramp, but the level side has a coefficient of friction of 0.30.
a. Draw the free-body diagram for each of the crates shown.
b. Find the value of m3, in order to achieve the acceleration above, if m1 = 100kg and m2 =20.0kg.
c. Find the tension on the cable between m3 and m2.
d. Find the tension on the cable between m2 and m1.
