A 5.50-kg object is initially moving so that its x-component of velocity is 6.00 m/s and y-component of velocity is -1.90
m/s.
(a) What is the kinetic energy of the object at this time?
(b) Find the change in kinetic energy of the object it its velocity changes so that its new x-component is 8.50 m/s
and its new y-component is 5.00 m/s.

4) An archer draws his compound bow and shoots an arrow. The 25 g arrow leaves the bow with a velocity of 95 m/s. The power stroke of the bow is 57 cm; that is, the bowstring exerts force on the arrow through a displacement of 57 cm. The peak draw weight of the bow is 312 N. (This is the maximum force that the archer has to exert on the bowstring.) a. How much kinetic energy does the arrow have after release? b. If shot straight up, how high will the arrow go?
A 2000 N net force acts right on a 5 kg object through a displacement of 2 m right. The initial velocity of the object is 50 m/s right.

calculate the train's final speed and energy lost with these numbers. A train car hits a three-car train; together, it becomes a four-car train. The mass of each train car is 40*103 kg. The initial speed of the single car is 3.3 m/s. The initial speed of the three-car train is 1.8 m/s.
A roller coaster car is initially at rest at the top of the track, 10 meters above the ground. The car is released and moves down the track. Calculate the velocity of the car when it is 2 meters above the ground. Use the conservation of mechanical energy.

Sterling Archer has given up Lacrosse and taken up pole vaulting. At the end of his approach run during a pole-vault, he has a horizontal velocity of 8 m/s and his center of gravity is 1.0 m high. If Archer has a mass of 50 kg, estimate how high he should be able to vault if his kinetic and potential energies are all converted to potential energy.
