Question

Two packing crates of masses m1 = 10.0 kg and m2 = 6.70 kg are connected by a light string that passes over a frictionless pulley as in the figure. The 6.70-kg crate lies on a smooth incline of angle 36.0

Two packing crates of masses m1 = 10.0 kg and m2 = 6.70 kg are connected by a light string that passes over a frictionless pulley as in the figure. The 6.70-kg crate lies on a smooth incline of angle 36.0 degree. Find the acceleration of the 6.70-kg crate (up the incline) in m/s2. Find the tension in the string in N.

Explanation / Answer

a) m1g - m2gsin36 = (m1 +m2)a

a = 3.56 m/s2

b) T = 10 g - 10a = 62.43 N
