A 93.5 kg ice hockey player hits a 0.150 kg puck, giving the puck a velocity of 43.0 m/s. If both are initially at rest and if the ice is frictionless, how far does the player recoil in the time it takes the puck to reach the goal 17.0 m away?

A 1400 kg car moving at 21 m/s runs into a 1200 kg car mobing in the same direction at 14 m/s. The two Cars lock together, and both drivers inmediately apply their brakes. If the cars comes to rest in 18 m, what is the coefficient of friction between the car's tires and the road?

A 98.3 kg archer is standing on level ice (neglect friction) fires a 97.3 g arrow to the right at 94.1 m/s. What is the recoil speed of the archer? (report your answer to at least the thousandth's place)

A rifle with a weight of 25 N fires a 4.9-g bullet with a speed of 270 m/s. (a) Find the recoil speed of the rifle. m/s (b) If a 600-N man holds the rifle firmly against his shoulder, find the recoil speed of the man and rifle. m/s

A 6.0 kg car is sitting on a floating 10 kg container in a lake and initially at rest 1.2 m away from the park. If the cat jumps back to the park, what is the minimum recoil speed of the box in the opposite direction? Assume the water and air friction are negligble and the dog travels in projectile motion.

A 20.0-kg toboggan with 58.3-kg driver is sliding down a frictionless chute directed θ = 27.6° below the horizontal at 7.70 m/s when a 55.0-kg woman drops from a tree limb straight down behind the driver. If she drops through a vertical displacement of 2.00 m, what is the subsequent velocity of the toboggan immediately after impact?

Identical twins, each with mass 52.5 kg, are on ice skates and at rest on a frozen lake, which may be taken as frictionless. Twin A is carrying a backpack of mass 12.0 kg. She throws it horizontally at 2.55 m/s to Twin B. Neglecting any gravity effects, what are the subsequent speeds of Twin A and Twin B?

A rocket ship is travelling through space. The fuselage section has a mass of 505 kg. The Nose Cone (front end) section has a mass of 100 kg. The rocket is travelling at 52.0 m/s when the rocket engine stops and the two sections are separated by an explosion in such a way that they stay in a straight line. If the Nose Cone section (front end) continues forward at 98.0 m/s, determine the speed of the Fuselage section after the separation.

A 48.1-kg person, running horizontally with a velocity of +3.23 m/s, jumps onto a 16.8-kg sled that is initially at rest. (a) Ignoring the effects of friction during the collision, find the velocity of the sled and person as they move away. (b) The sled and person coast 30.0 m on level snow before coming to rest. What is the coefficient of kinetic friction between the sled and the snow? (a) Number i (b) Number i Save for Later Units Units Attempts: 1 of 3 used Submit Answer

A rifle with a weight of 35 N fires a 5.5-g bullet with a speed of 270 m/s. (a) Find the recoil speed of the rifle. 0.386 x m/s (b) If a 675-N man holds the rifle firmly against his shoulder, find the recoil speed of the man and rifle. m/s
