• A man runs across the roof, top of a tall building and jumps horizontally with the
hope of landing on the root of the next building which is at a lower height than the
first. If his speed is 9 m/s, the (horizontal) distance between the two building is 10 m
and the height difference is 9 m, will he be able to land on the next building?
(Take, g = 10 m/s)

Answer 1

Let the angular velocity of shm be w. Then w= 2π/T. Now, if at t=0 particle is at mean position , it's displacement at any given time is .particle executing SHM with amplitude. A wil be equal when its displacement is: (a) Av2 (c) A/V2 (b) A/2 (d) Av2/3 - 296393A particle executing S.H.N. along a straight line has a velocity of um/s when its displacement from mean position is 3 m and 3 m / s when displacement is 4m. Find the time taken to travel 2.5 m from the positive extremity of its oscillation? oscillations
