A 17-kg cannonball is fired with a velocity of 15 m/s from 29 m above the ground. It hits a target that is 17 m above the ground. With what velocity does it hit, in m/s?

b.transmitters send radio waves, and receivers capture radio waves.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

elctricity and magnet is conversion to it
