At the instant a bullet (Bullet A) is being fired horizontally from a gun, an identical bullet (Bullet B) is dropped from the same height as the muzzle of the firing gun.
A softball coach throws a 1 kg ball horizontally to her player with an initial velocity of 40 m/s. The ball leaves her hand at 6 m high, and her catcher is 20 meters away.
An M-16 is fired from level ground at an upwards angle of 10 degrees with respect to the horizontal. The initial velocity of the bullet is 948 m/s, but because it is fired at a 10 degree angle, the vertical component of the initial velocity is 165 m/s and the horizontal component is 934 m/s. Ignore air resistance and the curvature of the earth in this problem.
The mass of Earth is 5.972 * 1024 kg, and the radius of Earth is 6,371 km. A 750 kg satellite orbits 35,800 km above Earth in a perfectly circular orbit.
