As shown in Figure CQ5.22, student A, a 55-kg girl, sits on one chair with metal runners, at rest on a classroom floor. Student B, an 80-kg boy, sits on an identical chair. Both students keep their feet off the floor. A rope runs from student As hands around a light pulley and then over her shoulder to the hands of a teacher standing on the floor behind her. The low-friction axle of the pulley is attached to a second rope held by student B. All ropes run parallel to the chair runners. (a) If student A pulls on her end of the rope, will her chair or will Bs chair slide on the floor? Explain why. (b) If instead the teacher pulls on his rope end, which chair slides? Why this one? (c) If student B pulls on his rope, which chair slides? Why? (d) Now the teacher ties his end of the rope to student As chair. Student A pulls on the end of the rope in her hands. Which chair slides and why? Figure CQ5.22
Construct Your Own Problem Consider an astronaut in deep space cut free from her space ship and needing to get back to it. The astronaut has a few packages that she can throw away to move herself toward the ship. Construct a problem in which you calculate the time it takes her to get back by throwing all the packages at one time compared to throwing them one at a time. Among the things to be considered are the masses involved, the force she can exert on the packages through some distance, and the distance to the ship.
Wood block 1 as shown, which has a mass of 1.0 kg, is at rest on a wood ramp. The angle of the ramp is 20° above horizontal. What is the smallest mass of block 2 that will start block 1 sliding uphill?a. 0.35 kg b. 0.83 kg c. 12. kgd. 1.9 kg e. 2.5 kg
A 0.020-kg bullet traveling at a speed of embeds in a 1.0-kg wooden block resting on a horizontal surface. The block slides horizontally 4.0 m on a surface before stopping. Determine the coefficient of kinetic friction between the block and surface. I know the solution is to first use 1) M1V1 + 0 = (M1+M2) Vf1 to get Vf1 = 5.9m/sThen use 2) net force = force of friction to get Uk However I'm confused why I couldn't use p + J = p for the second part after I got Vf1. In which case I would have (m1+m2)Vf1 + Ff*d = 0,(m1+m2)Vf1 = (m1+m2)g *Uk *dUk = Vf1/gdWhen I use this I get 0.15, which is the wrong answer. The right answer is 0.44. Can you help me identify the mistake in my logic? or if this is a way i could use but I'm just missing pieces? Thank you so much.

A 0.160 kg hockey puck is moving on an icy, frictionless, horizontal surface. At t = 0, the puck is moving to the right at 3.00 m/s. (a) Calculate the velocity of the puck (magnitude and direction) after a force of 25.0 N directed to the right has been applied for 0.050 s. (b) If, instead, a force of 12.0 N directed to the left is applied from t = 0 to t = 0.050 s, what is the final velocity of the puck?
Q7.The figure below shows two boxes connected to each other by a light cord that passes over a pulley with negligible friction. The box of mass m1 = 3.80 kg lies on a horizontal table with negligible friction, while the box of mass m2 = 10.3 kg hangs vertically. Two boxes labeled m1 and m2 are attached together by a cord. Box m1 lies on a horizontal table with the cord extending horizontally from its right side. The cord extends horizontally from the right side of m1 then goes over a pulley and then straight down to m2. Box m2 hangs from the cord. (a) What is the magnitude of the acceleration of each box (in m/s2)? (Here, a1 is the acceleration of m1, and a2 is the acceleration of m2.) a1 = m/s2 a2 = m/s2 (b) What is the tension in the cord (in N)? N
Skydiving tunnels have become popular attractions, appealing in part to those who would like a taste of the skydiving experience but are too overwhelmed by the fear of jumping out of a plane at several thousand feet. Skydiving tunnels are vertical wind tunnels through which air is blown at high speeds, allowing visitors to experience bodyflight. On Natalya's first adventure inside the tunnel, she changes her orientation and for an instant, her 46.8-kg body momentarily experiences an upward force of air resistance of 521 N. Determine Natalya's acceleration during this moment in time.
A small rocket for gathering weather data has a mass of 30 kg and generates 1500 N of thrust. On a windy day, the wind exerts a 20 N horizontal force on the rocket. If the rocket is launched straight up, what is the shape of its trajectory, and by how much has it been deflected sideways when it reaches a height of 1.0 km? Because the rocket goes much higher than this, assume there’s no significant mass loss during the first 1.0 km of flight.
A baseball approaches home plate at a speed of 40.0 m/s, moving horizontally just before being hit by a bat. The batter hits a pop-up such that after hitting the bat, the baseball is moving at 50.0 m/s straight up. The ball has a mass of 145 g and is in contact with the bat for 2.50 ms. What is the average vector force the ball exerts on the bat during their interaction? (Let the +x-direction be in the initial direction of motion, and the +y-direction be up.)
Multiple correct: The cart of mass 10 kg shown above moves without frictional loss on a level table. A 10 force pulls on the cart horizontally to the right. At the same time, a 30 N force at an angle of 60° above the horizontal pulls on the cart to the left. Which of the following describes a manner in which this cart conld be moving? Select two answers.

Two objects ( m1 = 5.00 kg and m2 = 3.00 kg) are connected by a light string passing over a light, frictionless pulley as in Figure P5.71. The 5.00-kg object is released from rest at a point h = 4.00 m above the table. (a) Determine the speed of each object when the two pass each other. (b) Determine the speed of each object at the moment the 5.00-kg object hits the table. (c) How much higher does the 3.00-kg object travel after the 5.00-kg object hits the table?
