The string connecting the m1 and the m2 passes over a light frictionless pulley. given m1 = 3.73 kg, m2 = 8.28 kg, m3 = 1.17 kg, and g = 9.8 m/s 2 . the acceleration of gravity is 9.8 m/s 2 . find the downward acceleration of m2 mass. answer in units of m/s 2

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

explanation:

-reverse card

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
