###### Answers:

Correct Option (c) 6.33 sec

Explanation:

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
