Given that, Velocity v=um/s Time taken to reach at maximum height t1=5s Now, Total time taken to reach same point t2=9s Particle to reach its maximum height will be half of total time =4.5s Now, the particle returns to the same point in time t=9−5=4s Now, the time at height is t=4.5−4 t=0.5s So, the velocity at height h v=u−gt 0=u−9.8×0.5 u=4.9m/s Hence, the speed of the particle at height is 4.9 m/s
