Two packing crates of masses 10.0 kg and 5.00 kg are con- nected by a light string that passes over a frictionless pul- ley as in Figure P4.60. The 5.00-kg crate lies on a smooth incline of angle 40.0°. Find (a) the acceleration of the 5.00-kg crate and (b) the ten- sion in the string. 5.00 kg 10.0 kg 40.0° Figure P4.60
