How do I solve this Physics Problem?

Question

A shell is fired from a gun whose barrel is elevated 20.0° above the horizontal. The muzzle velocity of the shell is 245m/s. Calculate the verticle and horizontal components of the muzzle velocity

Answer 1

You need to project the muzzle velocity in the horizontal (x) and vertical (y) directions.

 

v_x = v cosθ = 245cos20.0° m/s = ? m/s

 

v_y = v sinθ = 245sin20.0° m/s = ? m/s
