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...
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...
You are pulling a child on a sled across a frozen pond (the ice makes it frictionless). The mass of the child-plus-sled is 20kg, and you exert a force of 40N for 3 seconds, starting from rest. (a) What is the acceleration of the sled? (b) How far does the sled go? (c) How fast is it going, at the end? (d) How much work did you do? (e) What is the final kinetic energy of the sled-plus-child? (f) What...
Can you check if I did the problem correctly? Or is there
another way to do this? What why is the correct way to answer part
C, the second image or the third image. Thank you for your help
7. A 40-kg girl and an 8.4-kg sled are on the surface of a frozen lake, 15 m apart. By means of a rope the girl exerts a 5.2-N force on the sled, pulling it toward her. (a) What is the...
A sled and rider, gliding over horizontal, frictionless ice at 4.8 m/s , have a combined mass of 72 m/skg . The sled then slides over a rough spot in the ice, slowing down to 2.8m/s . What impulse was delivered to the sled by the friction force from the rough spot?
You are about to ride a steel sled down a surface of ice with an incline of 50 degrees to the horizontal and a distance of 200 m to the bottom of the hill. Draw a free-body diagram for the instant it starts moving. What is the resulting force and acceleration the instant after it starts moving? What is the velocity at the bottom of the hill (initial velocity=0) mus of s= 0,03, mus of k= 0.015. The total mass...
1. The figure shows a box with mass m1 on a
frictionless plane inclined at angle ?1. The
box is
connected via a cord of negligible mass to another
box with mass m2 on a frictionless plane
inclined at
angle ?2 (> ?1). The pulley
is frictionless and has
negligible mass and assumes that the setup is on the
surface of the earth.
a) Provide free-body force diagram for both boxes.
b) What is the acceleration in terms of m1,...
A 54-kgkg woman and a 79-kgkg man stand 11 mm apart on frictionless ice. 1) How far from the woman is their CMCM? Express your answer using two significant figures. 2) If each holds one end of a rope, and the man pulls on the rope so that he moves 3.0 mm , how far from the woman will he be now? Express your answer using two significant figures. 3) How far will the man have moved when he collides...

Express your answer using two significant figures. 2CM = 7.5 m Submit Previous Answers Correct Part B Each person holds the end of a rope and the man pulls on the rope so that he moves toward the woman. How far will the man have moved when he collides with the woman? Express your answer using...
1.A block of mass m = 5.00 kg is pulled along a horizontal frictionless floor by a cord that exerts a force of magnitude F = 12.0 N at an angle θ = 25o . (a) Draw the free body diagram of the block. (b) Find the normal force. 2.Two crates are at rest on frictionless horizontal surface. Both crates are connected by a light rope. A woman wearing golf shoes (so she can get traction on the ice) pulls...
