Objects of masses m1=4.00kg and m2 = 9.00kg are connected by a light string that passes over a frictionless pulley. the object m1 is held at rest on the floor, and m2 rests on a fixed incline of (theta)=40.0 degree. the objects are released from rest, and m2 slides 1.00m down the incline in 4.00s. determine a) the acceleration of each object, b) the tension in the string, and c) the coefficient of kinetic friction between m2 and he incline.

The acceleration of each object is

Acceleration is velocity rate of change of of an object with respect to time. An object's acceleration is the net result of all forces acting on the object, as described by Newton's Second Law. Whereas kinetic friction is a force that acts between moving surfaces. Then tension is the pulling force transmitted axially by the means of a string, a cable, chain etc
