6. A hockey puck is accelerated, using a hockey stick, over a smooth, level ice surface. The puck has a mass of 0.40 kg and is moved by the stick for a distance of 0.80 m. What was the force applied to the
puck if the speed is 25 m/s?

What’s #16 asking and how do i solve it?

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
