A 36 kg girl and a 9 kg sled are on the frictionless ice of a frozen lake, 20 m apart but connected by a rope of negligible mass. The girl exerts a horizontal force of 6 N on the rope. a. What is the acceleration of the center of mass of the girl-sled system when the girl exerts a 6 N force on the rope? b. How far from the girl’s initial position do they meet? please explain each...

A 41 kg girl and a 6.5 kg sled are on the frictionless ice of a frozen lake, 18 m apart but connected by a rope of negligible mass. The girl exerts a horizontal 4.5 N force on the rope. What are the acceleration magnitudes of (a) the sled and (b) the girl? (c) How far from the girl's initial position do they meet? I really only need part (c). I have (a) = .6923 N and (b) = .1097...

Physics Girl is standing on her skates on a frozen pond when Einswine, moving with a uniform velocity of 18 m/s, skates by with the hockey puck. 2.1 s after Einswine passes her, Physics Girl makes up her mind to chase Einswine and accelerates towards him with a constant acceleration. Physics Girl catches up to Einswine 10.0 s after she began to move. What was the magnitude of Physics Girl’s acceleration? (Assume Einswine remains in motion at constant velocity.)

Problem 4.39
Two crates, one with mass 4.00 kg and the other with mass 6.00 kg, sit on the frictionless surface of a frozen pond, connected by a light rope (Figure 1). A woman wearing golf shoes (so she can get traction on the ice) pulls horizontally on the 6.00 kg crate with a force F that gives the crate an acceleration of 290 m/s 6.00 kg よ 00 kg T he woman is pulling two c rope that connects...

A 66 kg water skier is being accelerated by a ski boat on a flat ("glassy") lake. The coefficient of kinetic friction between the skier's skis and the water surface is μk = 0.28.What is the skier's acceleration if the rope pulling the skier behind the boat applies a horizontal tension force of magnitude FT = 240 N to the skier (θ=0∘)? Express your answer to two significant figures and include the appropriate units. a A =???? What is the...

9. A girl is dragging a suitcase along a rough surface by pulling horizontally on a rope that is attached to it. Draw a free body diagram for the suitcase. If the coefficient of kinetic friction is 0.54 and the mass of the suitcase is 20 kg, and the girl is pulling with a force of 200 N find the horizontal accelłeration of the suitcase.

A contestant in a winter games event pushes a 32.0-kg rock across a frozen lake with a force of 25 Nat 24" below the horizontal as shown in Figure (ə) below, and it moves with an acceleration of 0.71 ms to the right. (a) What is the normal force (in N) exerted by the lake surface on the rock? (b) Instead of pushing on the rock, the contestant now pulls on it with a rope over his shoulder at the...
