A jet aircraft with a mass of 4,325 kg has an engine that exerts a force (thrust) equal to 60,800 N.
(a) What is the jet's acceleration? (Give the magnitude.)
(b)What is the jet's speed after it accelerates for 7 s? (Assume it starts from rest.)
(c) How far does the jet travel during the 7 s?
Now imagine a baseball exits the launcher with a great deal of spin. You may select the angle of the spin. What would happen to the ball's trajectory? Offer an explanation as to why.
