The space shuttle launches an 850-kg satellite by ejecting it from the cargo bay. The ejection mechanism is activated and is in contact with the satellite for 4.8 s to give it a velocity of 0.30 m\s in the x direction relative to the shuttle. The mass of the shuttle is 92,000 kg.

(a) Determine the component of velocity vf of the shuttle in the minus x direction resulting from the ejection.

(b) Find the average force that the shuttle exerts on the satellite during the ejection.
