Two packing crates of masses m1 = 10.0 kg and m2 = 6.50 kg are connected by a light string that passes over a frictionless pulley as in Figure P4.26. The 6.50 kg crate lies on a smooth incline of angle 39.0°.

Question

a)Find the acceleration of the 6.50 kg crate.
m/s2 (up the incline)

b)Find the tension in the string.
N

Answer 1

m1 and m2 will have the same acceleration rate magnitude, but it will be in difference directions.

Draw free body diagrams of m1 and m2 write two simultaneous equations of motion (one for each mass). The unknowns will be string tension T and acceleration rate a.
