A ball is fired with a velocity of 12 meters per second from a cannon?

Question

A ball is fired with a velocity of 12 meters per second from a cannon pointing north, while the cannon is moving eastward with a velocity of 24 meters per second. Which vector best represents the resultant velocity of the ball as it leaves the cannon

Answer 1

I dare say d, since eastward velocity is greater than the northward one

Answer 2

12/24=.5

N=12, E=24 Tan^-1(.5)=26.5

D

Answer 3

↑v = 24î + 12ĵ m/s

θ = arctan(12/24) = 26.5° from the positive horizontal

Answer D
