Two packing crates of masses 10.0 kg and 5.00 kg are connected by a light string that passes over a frictionless pulley. The 10.0 kg crate lies on an incline of angle 40.0° with a coefficient of kinetic friction 0.250.
a) Find the acceleration of the crates.
b) Find the tension in the string between the crates.
c) If the 10.0 kg crate starts from rest at the top the incline, how long does it take to reach the bottom of the incline? Assume the incline is 10.0 m long?
