A projectile travels with a projectile speed of 200m/s at an angle of pie/4 radians to the horiztonal. calculate the x and y components of the speed.

Question

I need help with this question

Answer 1

Just find the x and y components of the velocity vector.  At that particular instant,

 

v_x = v cosθ = (200 m/s)cos(π/4) = ? m/s

 

v_y = v sinθ = (200 m/s)sin(π/4) = ? m/s
