The force that does the accelerating presumably stays the same. The acceleration rate drops by the same ratio that the total mass rises. That ratio is 5.
(MB + MA)/MA = 5
MB = 4 MA
Block a is moving with a certain acceleration along a frictionless horizontal surface. When a second block B is placed on top of block A, the acceleration of the combined block drops to 1/5 the original value. What is the ratio of the mass of A to the mass of B :
