Question

The cannon on a battleship can fire a shell a maximum distance of 33.0 km.

(a) Calculate the initial velocity of the shell.

Answer 1

v = 804.23 m/s

Step-by-step explanation:

Given that,

The maximum distance covered by a cannon, d = 33 km = 33000 m

We need to find the initial velocity of the shell. Let it is v. It can be calculated using the conservation of energy such that,

`v=√(2gh) \\\\v=√(2* 9.8* 33000) \\\\v=804.23\ m/s`

So, the initial velocity of the shell is 804.23 m/s.
