8*6.2= 60.76m.Theeeeen draw a diagram with horizontal and vertical components, use pythag to find the hypotenuse (resulting velocity) which should be 65.4ms-1 then finally find the angle using one of the trig formulas.......
A body is projected form a certain height horizontally and reaches the ground in 6.2 seconds. Find the resultant velocity.

I found the height: 188 m
Range: 150 m

How to find the resultant velocity

-
Range: 150
time: 6.2s
Therefore:
Horizontal velocity= s/t =150/6.2 = approx. 24.2m.s^-1

Vertical velocity: v0 + at = 0+ 9.8*6.2= 60.76m.s-1

Theeeeen draw a diagram with horizontal and vertical components, use pythag to find the hypotenuse (resulting velocity) which should be 65.4ms-1 then finally find the angle using one of the trig formulas.
