Sound travels faster in

What travels faster : a radio signal or sound in air ?

A bullet is fired from a rifle that is held 1.6 m above the ground in a horizontal position. The initial speed of the bullet is 1100 m/s. Find the time it takes for the bullet to strike the ground and the horizontal distance traveled by the bullet.

Sound travels faster in iron than in air.

A rifle man, who together with his rifle has a mass of 100 kg, stands on a smooth surface and fires 10 shots horizontally. Each bullet. has a mass 10 g and a muzzle velocity of 800 m//s , a. What velocity does the rifle man acquire at the end of 10 shots? b. If the shots are fired in 10 s , what will he the average force exerted on him? c. Compare his kinetic energy with that of 10 bullets
