Question
"Relative" is an important word. In the figure below, block L of mass mL = 2.00 kg and blockR of mass mR = 0.500 kg are held in place with a compressed spring between them. When the blocks are released, the spring sends them sliding across a frictionless floor. (The spring has negligible mass and falls to the floor after the blocks leave it.)
"Relative" is an important word. In the figure below, block L of mass mL = 2.00 kg and blockR of mass mR = 0.500 kg are held in place with a compressed spring between them. When the blocks are released, the spring sends them sliding across a frictionless floor. (The spring has negligible mass and falls to the floor after the blocks leave it.) If the spring gives block L a release speed of 1.40 m/s relative to the floor, how far does block R travel in the next 0.800 s? If, instead, the spring gives block L a release speed of 1.40 m/s relative to the velocity that the spring gives blockR, how far does block R travel in the next 0.800 s?Explanation / Answer
speed of block R = momentum of L / Mass of R = 2 *1.4 / 0.5
speed of R = 5.6 m/s
distance R moves in 0.8s = 5.6 . 0.8 = 4.6 m = 4.6 m
B) vr + vl= 1.4
Mr.Vr + Ml.Vl = 0
0.5 . Vr =
