A 88.0 kg ice hockey player hits a 0.150 kg puck, giving the puck a velocity of 46.0 m/s. If both are initially at rest and if the ice is frictionless, how far (in m) does the player recoil in the time it takes the puck to reach the goal 17.0 m away? (Enter the magnitude.)

Kyle, a 80.0 kg football player, leaps straight up into the air (with no horizontal velocity) to catch a pass. He catches the 0.430 kg ball precisely at the peak of his jump, when he is 0.437 m off the ground. He hits the ground 0.0358 m away from where he leapt. If the ball was moving horizontally when it was caught, how fast u was the ball traveling? Vs m/s

A rocket, which is in deep space and initially at rest relative to an inertial reference frame, has a mass of 75.8 x 105 kg, of which 15.3 × 105 kg is fuel. The rocket engine is then fired for 410 s, during which fuel is consumed at the rate of 390 kg/s. The speed of the exhaust products relative to the rocket is 2.81 km/s. (a) What is the rocket's thrust? After the 410 s firing, what are (b) the mass and (c) the speed of the rocket? (a) Number i Units (b) Number i Units (c) Number i Units

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

Male bighorn sheep (120 kg ) engage in head-butting contests to establish dominance. High-speed photography has shown that the impact speed is typically 6.0 m/s and that the collision, which brings both rams to a halt, lasts approximately 0.25 s . Suppose the collision force increases linearly with time until it reaches a maximum Fmax , then decreases linearly to zero at t = 0.25 s.  What is Fmax?

. The fisherman's mass is 79 kg, and the boat's is 126 kg. The fisherman and boat are initially at rest when the fisherman throws a package of mass m = 15 kg horizontally to the right with a speed of vi = 4.9 m/s. What is the velocity of the boat after the package is thrown? Neglect any resistance force from the water. (Give the magnitude in m/s, and select the correct direction from the options given.)  What is the direction of the boat?

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?

A woman weighing 57.1 kg stands at one end of a 120-kg raft that is 6.00 m long. The other end of the raft is 0.500 m from a pier. So, before the woman moves, she is at a total distance of 6.50 m away from the pier. The woman walks toward the pier until she gets to the other end of the uniform raft and stops there. What is the distance between the uniform raft and the pier?
