Question

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?

Explanation / Answer

1.)a=v^2/R=148^2/382=57.34=5.85g

2.)48.8=mv^2/R

v=sqrt(48.8*42300000/190.3)=3293.52m/s

3.)0.05*600=7.45*v

v=4.0268m/s
