Ball Is Projected Upwards From Top Of Tower With Velocity Making Angle 30в° With Horizontal

A ball is projected upwards from the top of tower with a velocity 50 m/s making angle 30° with the horizontal. The … sec (c) 6.33…


Correct Option (c) 6.33 sec


Formula for calculation of time to reach the body on the ground from the tower of height ‘h’ (If it is thrown vertically up with velocity u) is given by

So we can resolve the given velocity in vertical direction and can apply the above formula. 

Initial vertical component of velocity usinθ = 50 sin30 = 25 m/s
