Question
A particle when thrown,moves such that it passes from same height at 2sec. And 4 sec, then what is the height?Joshi sir comment
Due to gravity a freely falling body covers the distances in the ratio 1:3:5:7:9..............................so
if a particle passes at the same point twice (2nd and 4th sec), then it will be at heightest pont in 3rd sec. so height = 5+15+25 = 45 meter
