The same horizontal force, of magnitude F, is applied to two different blocks, of mass m and 3m The blocks move on a frictionless surface and both blocks begin from rest. If each block moves the same distance as the force is applied, which one of the following sentences is true? O The heavier block acquires 3 times as much kinetic energy as the lighter block. The heavier block acquires 9 times as much kinetic energy as the lighter block. The two blocks acquire the same kinetic energy, The lighter block acquires 9 times as much kinetic energy as the heavier block, The lighter block acquires 3 times as much kinetic energy as the heavier block.

Answer 1

Here different, and marses are acceleration =E face is same so m so, a,= Ll and a, :f = A=1 a 3m 3 2 Now so 19,=3a2 v²_4²=2a8 (As uso initialley u?= 2a8 V=4298. And Kinetic energy = 1 mu? Now for m, ke 1 m. 2xsxa, = msan. and for 3 m, 19. f = { x 8m x 2xstal = msa, " the kinetic energy of both 3 block ale same.
