Question

A block A of mass m1 is released from top of smooth inclined plane and it slides down the plane. Another block of mass m2 such that m2 > m1is dropped from the same point and falls vertically downwards. Which one of the following statements will be true if the friction offered by air is negligible?

Answer:

A block A of mass m1 is released from top of smooth inclined plane and it slides down the plane. Another block of mass m2 such that m2 > m1is dropped from the same point and falls vertically downwards. Which one of the following statements will be true if the friction offered by air is negligible?

Explanation:

Consider u and v be the initial and final velocity of the block.

Then, by applying equations of motion we can write:

V 2 =u 2 +2asV 2

=0+2(gsinθ) sinθh ⇒V 2

=2gh⇒V= 2gh
