good night,
we are new in this forum.
we have a physics question about parabolic trajectory...
when a projectile is thrown with a certain angle, with initial v_0x and v_0y speeds, the trajectory of this projectile will be a parabola...
the initial x and y velocities will be:
[tex]v_{0x}=vcos\theta[/tex]
[tex]v_{0y}=vsen\theta[/tex]
and the x and y velocities after a certain time will be:
[tex]v_{x}=v_{0}t[/tex]
[tex]v_{y}=v_{0y}-gt[/tex]
is it right?
but here is our doubt:
we were wondering how we could calculate the work of this projectile.
could it be:
[tex]\tau=Fx=Fv_{0}t[/tex]?
if our English is not very expressive, it's because we're Brazilian... we're not native English speakers.
thank you in advance,
