A particle when thrown vertically upward, moves such that it passes from same height at t = 2s and t = 10s, then this height is :
10 m
20 m
50 m
100 m
At time t = 2 sec and t = 10 sec, initial velocity = u a = -g By equation of motion (at t = 2 sec) s = ut + h = 2u - 2g ...(1) at t = 10 sec h = 10 u - 50 g ...(2) From equation (1) & (2)
h = 100 m
