Projectile physics question

I’ve created a very simple ballistics game, where a projectile can be thrown with varying force along a scrolling background - very much along the lines of a ‘penguin throwing’ game. So far so good… but at the moment the projectile moves with an initial x and y velocity, and what I would prefer is for the user to be able to input an angle and force of throw.

Could anyone enlighten me on how to calculate the x and y velocities, given an angle of throw from the horizontal and a force of throw?

Thanks in advance to any who’s able to help
