Two packing crates of masses

m1 = 10.0 kg

and

m2 = 4.70 kg

are connected by a light string that passes over a frictionless pulley as in the figure below. The 4.70-kg crate lies on a smooth incline of angle 35.0°. Find the following.

Two crates are connected to each other by a string that passes over a pulley, which is attached to the top corner of a wedge. The crate of mass m1 hangs freely below the pulley. The crate of mass m2 rests on the wedge's inclined surface that makes an angle θ with the horizontal.

(a) the acceleration of the 4.70-kg crate
m/s2 (up the incline)

(b) the tension in the string
N
