Question

A cannonball is fired from a cannon on top of a castle wall with a vertical speed of 18 m/s and a horizontal speed of 27 m/s. If it takes 12 seconds for the cannonball to hit the ground, how far away will it be from the wall?

Answer 1

You have to use DST formula

D=distance

S=speed

T=time

Ok you need to find the distance.

don't touch this 27m/s

Speed=18

time=12

now u need to tmes them

18 times 12=216m

this is the answer

is easy right
