What is the final speed of the ball of putty
A 10.11 g ball of putty traveling east at 5.24 m/s collided and sticks to another ball of putty of mass 26.22 g traveling north at 10.05 m/s. What is the final speed (magnitude) of the ball of putty?

A baseball pitcher throws a 145 g baseball parallel to the ground with a speed of 36.29 m/s in the +x direction. The batter imparts an impulse of -9.59 to the ball so that the ball returns along the same path in the -x direction. What is the veloc
It is observed that when a regulation 20 ounce basketball is dropped from a height of 1.3m onto a floor. If it is desired to have the basketball return to its initial elevation, what initial downward velocity must be applied when it is dropped?
A baseball batter swings the bat and applies a force of 66.95 N to the ball for a time of 0.36 s. Assuming the force is constant, what is the impulse on the ball?
Maddox takes off on his jet ski so they have a combined mass of 334.97kg. The skis have a thrust of 1,087.97N and a coefficient of kinetic friction on snow of 0.07. Maddox failed to check the gas tank and ran out of gas after only 10.88 s. What is

A cyclist is traveling at 8m/s when she encounters a hill with 2% grade (assume the elevation increases by 2' for every 100' of travel). How much energy is required to climb the hill?
Two metal balls are hung from strings. The first ball, 0.09 kg, is pulled to the side and released so that it strikes the second ball with a speed of 1.62 m/s.
Write down the equations expression the conservation of momentum for the components in the x and y directions separately. (b) Solve these equations for the speed V'b and angle Theta'b of ball B. Do not assume the collision is elastic.
