Two objects with masses of m1 = 3.60 kg and m2 = 5.80 kg are connected by a light string that passes over a frictionless pulley
a. Determine the tension in the string. (enter the magnitude only and do not use rounded intermediate values in your calculations)
b. Determine the acceleration of each object. (Enter the magnitude only.)
c. Determine the distance each object will move in the first second of motion if both objects start from rest.
