Question

The projectile is fired with an initial velocity 40 m/s at an angle of elevation of 30degrees on a platform, find the x and y components of the velocity at t=0

Answer 1

There are two simple equations we use to find this out in algebra-based physics. One finds the x component and the other the y with only the input of the initial velocity and the firing angle. Both of which you have! Yay!
\[v_{0x} = v_{0} \cos \theta_{0}\]
and
\[v_{0y} = v_{0} \sin \theta_{0}\]
Substitute your values into those equations and solve:
\[v_{0x} = 40 \cos 30 = 34.64\]
and
\[v_{0y} = 40 \sin 30 = 20\]
Tada! :)
