An air-track glider with mass m1 is moving on a level, frictionless air track in the physics lab. The glider is connected to a lab weight with mass m2 by a light, flexible, nonstretching string that passes over a stationary, frictionless pulley. Find the acceleration of each object.

1 a

2 b

3 b

4 d

5 d

6 d

explanation:

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
