*23. Go The lead female character in the movie Diamonds Are Forever is standing at the edge of an offshore oil rig. As she fires a gun, she is driven back over the edge and into the sea. Suppose the mass of a bullet is 0.010 kg and its velocity is +720 m/s. Her mass (including the gun) is 51 kg. (a) What recoil velocity does she acquire in response to a single shot from a stationary position, assuming that no external force keeps her in place? (b) Under the same assumption, what would be her recoil velocity if, instead, she shoots a blank cartridge that ejects a mass of 5.0 × 10-4 kg at a velocity of +720 m/s?

A 52.1-kg person, running horizontally with a velocity of +4.62 m/s, jumps onto a 14.7-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) Numberi Units

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

The fisherman's mass is 70 kg, and the rowboat's is 119 kg. The fisherman and rowboat are initially at rest when the fisherman throws a package of mass m = 15 kg horizontally to the right with a speed of vi = 4.7 m/s. What is the velocity of the rowboat 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.) A fisherman in a rowboat throws a package of mass m to the right with velocity vector vi. magnitude                       m/s toward what direction

A 74.6-kg person, running horizontally with a velocity of +4.47 m/s, jumps onto a 11.4-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: 0 of 3 used Submit Answer

A 44.0-kg girl is standing on a 157-kg plank. Both originally at rest on a frozen lake that constitutes a frictionless, flat surface. The girl begins to walk along the plank at a constant velocity of 1.461 m/s relative to the plank. (a) What is the velocity of the plank relative to the ice surface? 1 m/s (b) What is the girl's velocity relative to the ice surface? 1 m/s Need Help? Read It Master It

Starting from rest, two skaters push off against each other on ice where friction is negligible. One is a 64.0 kg woman and one is a 93.0 kg man.  The woman moves away with a velocity of +2.83 m/s.  Find the recoil velocity of the man.  Group of answer choices

A 90.0 kg fullback running 36.9° north of east with a speed of 5.00 m/s is tackled and held onto by an 60.4 kg opponent running north with a speed of 5.34 m/s. What is the magnitude of the velocity of the players immediately after the tackle?

A 42.3-kg person, running horizontally with a velocity of +2.09 m/s, jumps onto a 17.5-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.
