A 45.0 kg girl is standing on a 159 kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.38 m/s relative to the plank. (a) What is her velocity relative to the surface of ice? 1 m/s (b) What is the velocity of the plank relative to the surface of ice? 2 m/s

A 48.8 kg girl is standing on a 136 kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.59 m/s relative to the plank. What is her velocity relative to the ice surface? What is the velocity of the plank relative to the ice surface?

A 45.0-kg girl is standing on a 130-kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.59 m/s to the right relative to the plank. (Let the direction the girl is moving in be positive. Indicate the direction with the sign of your answer.) (a) What is her velocity relative to the surface of ice?...

A 40.7 kg girl is standing on a 151 kg plank. Both are 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 1.56 m/s x̂ relative to the plank. (a) What is the velocity of the plank relative to the ice surface? (b) What is the girl's velocity relative to the ice surface?

Liquid saline flows steadily along the duct in Figure 1, which is part of an infusion set. The duct has constant cross-sectional area Ao-18 mm. The fluid velocity at the inlet section is Vo 0.35 m/s. A drug is added to the saline through a side port connected to the main duct at an angle θ 45°. The cross-sectional area of the side access is A1-10 mm2 and the drug is injected with velocity V,-0.8 m/s. The drug has the...

1. Determine whether the statements below are true or false: a. [4 points) Two carts move in the same direction along a frictionless track, each acted upon by the same constant impulse. If Cart 1 has the twice the mass of Cart 2, then Cart 2 will have the greater change in linear momentum. b. [4 points) Any force component that causes a centripetal acceleration cannot change the translational kinetic energy of the object. c. [4 points) A...
