An m1 = 8.9 kg block and an m2 = 10.1 kg block, connected by a rope that passes

Question

An m1 = 8.9 kg block and an m2 = 10.1 kg block, connected by a rope that passes over a frictionless peg, slide on frictionless incline.

(a) Find the acceleration of the blocks and the tension in the rope.

a = ? m/s2

T = ? N

(b) The two blocks are replaced by two others of masses m1 and m2 such that there is no acceleration. Find whatever information you can about the masses of these two new blocks.

m1/m2 =?

Explanation / Answer

a). let m1 moves down the incline m1gsin40-T=m1a T-m2gsin50=m2a a=-1.04 m/s^2 that means block m1 moves up the incline and T=65.38 N b) m1gsin40=m2gsin50 m1/m2 =1.19
