Tossing Rocks on Frictionless Ice: Calculating Angle and Speed

In summary, frictionless ice is a surface with no resistance or friction, making it an idealized surface for studying projectile motion. The angle and speed of tossing rocks on frictionless ice can be calculated using the principles of physics and can be affected by factors such as initial force, mass and shape of the object, and the surface of the ice. This knowledge can have practical applications in sports and engineering.

While standing on frctionless ice, you (mass 65.0 kg) toss a 4.5 kg rock with initial speed 12.0 m/s. IF the rock is 15.2 m from you when it lands, (a) at what angle did you toss it? (b) How fast are you moving?

I'm still having trouble with these.
