Answer 1

d = 421.83 m

Step-by-step explanation:

It is given that,

Height, h = 396.9 m

Horizontal speed, v = 46.87 m/s

We need to find the distance traveled by the ball horizontally. Let t is the time taken by the ball. Using second equation of motion for vertical direction. So,

`396.9=0* t+(1)/(2)* 9.8 t^2\\\\t=9\ s`

Now d is the distance covered by the cannonball. So,

`d=vt\\\\d=46.87* 9\\\\d=421.83\ m`

Hence, this is the required solution.
