MHT CET Physics question

PhysicsOscillationsMHT CET

A body is oscillating vertical about its mean position. If its maximum and minimum heights above the surface of the ground are 2 m and 1.5 m, then the speed at the mean position will be (g = 10 )

Answer: (B)

Solution

The amplitude is A = 0.25 m; taking the motion to be governed by gravity alone ( A = g) the speed at the mean position is
