What is its impact speed

Reference no: EM13487199

Block A (m = 1.20 kg), originally at rest, is pushed with a net horizontal force of 7.86 N for 5.34 m as it slides across a horizontal, frictionless surface. Then the force is removed and the Block A slides up a frictionless slope to another horizontal, frictionless surface, gaining 1.60 m in altitude as a result. On the upper surface, block A collides with block B (m = 2.34 kg), which is sitting at rest, and the two blocks stick together thereafter. The combined block AB continues to move at some constant speed until it comes to the abrupt edge of the surface and falls freely to the floor, 6.57 m below. Ignore any rotational motion or air resistance.

(i) At what horizontal distance does block AB land on the floor, measured from the abrupt edge?

(ii) What is its impact speed?
