Question

Blocks A and B are connected across a frictionless pulley by a cord of negligible weight. If block B lies on a horizontal, frictionless surface and block A hangs vertically, what can be said about the acceelration of block B? A) It would accelerate at approximately 9.8 m/s2 B) It would accelerate at some constant rate other than 9.8 m/s2 C) Its rate of acceleration would increase with time. D) Its acceleration would be a function of the initial velocity of block A. E) It would not accelerate, but rather move with a constant velocity.

Explanation / Answer

B) It would accelerate at some constant rate other than 9.8 m/s2
