A stone is projected horizontally with 20m/s from the top of a tall building. Calculate its position and velocity after 8 second neglating air registance.​

Gam radio signals can usually be heard behind a hill, but fm often cannot. that is, am signals bend more than fm. explain. (radio signals, as we shall see, are carried by electromagnetic waves whose wavelength for am is typically 200 to 600 m and for fm about 3 m.)

The force will determine the acceleration.
