JEE Main 6 April 2026, Shift 2, Physics Q44

Question 44 of 75 in this shift, Physics question 19 of 25, Section A.

The velocity at which 6 kg mass (shown in figure) strikes the ground when it is released from a height of 6 m above the ground is __________ m/s. Assume pulley is massless and string is light and inextensible. (Take g = 10 m/s2^2)

The figure, in words

Massless pulley hung from the ceiling with a string over it; a 6 kg block on the left hangs 6 m above the ground, a 2 kg block on the right rests on the ground.
