1. A pilot will black out if experiencing a centripetal acceleration of greater than 5g s. An F-16 going 148 m/s enters a tight turn of radius 382 m. The pilot in this case is experiencing how many g's?
2. A 190.3 kg satellite is in a circular orbit of 26,273 miles (42,300,000 m) in radius. The force keeping the satellite in orbit is 48.8 N. What is the velocity (speed) of the satellite?
3. A 0.05 kg bullet traveling at 600 m/s hits a 7.4 kg block of wood and stays in the wood. What is the velocity (speed) of the wood block immediately after the bullet hits it?
