A Bomber flying upward at an angle of `53^@` with the vertical releases a bomb at an altitude of 800 m. The bomb strikes the ground 20 sec after its release. Find :
the velocity (magnitude and direction) of the bomb just when it strikes the ground.
(`sin 53^@ = 0.8, g =10m/s^2`]

Text Solution

Verified by Experts

`theta = tan^-1(7/4)` `V = `20sqrt(65) m/s`]
