Multiple-object systems with friction: Two boxes are connected by a weightless cord running over a very light frictionless pulley as shown in the figure. Box A, of mass 8.0 kg, is initially at rest on the top of the table. The coefficient of kinetic friction between box A and the table is 0.10. Box B has a mass of 15.0 kg, and the system begins to move just after it is released. A B (a) Draw the free-body diagrams for each of the boxes, identifying all of the forces acting on each one. (b) Calculate the acceleration of each box. (6.1 m/s²) (c) What is the tension in the cord? (56 N)
A child of mass 30kg swings at the end of an elastic cord. At the bottom of the swing, the child's velocity is horizontal, and the speed is 9.8m/s. At this instant, the cord is 5.85m long. A) at this instant what is the magnitude of the rate of change of the child's momentum? B) at this instant what is the net force acting on the child? C) what is the magnitude of the force that the elastic cord exerts on the child? D) the relaxed length of the elastic cord is 5.78m. What is the stiffness of the cord?
An unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only a rope and a bag of tools. First he tries to throw a rope to his fellow astronaut, but the rope is too short. In a last ditch effort, the astronaut throws his bag of tools in the direction of his motion, away from the space station. The astronaut has a mass of ma = 113 kg and the bag of tools has a mass of m the space station at v¡ = 1.80 m/s. = 10.0 kg. The astronaut is moving away from What is the minimum final speed Ubf of the bag of tools with respect to the space station that will keep the astronaut from drifting away forever? Ub,f = m/s
1. A hose sprays water into a train car. The hose is fixed in place and directed along the tracks, and the train car can move along the tracks without friction. The hose sprays water at a fixed rate a ([a] =MT-1) and speed v; the mass of the empty car is M. If the train car starts empty and at rest at t = 0, what is its speed at time t?
A stationary 2.17-kg object is struck by a stick. The object experiences a horizontal force given by F = at - bt 2, where t is the time in seconds from the instant the stick first contacts the object. If a = 1,500,000 N/s and b = 20,000,000 N/s?, what is the speed of the object just after it comes away from the stick at t = 2.55 x 103 s? %3D
Pretend you are standing on roller skates and toss a football. If the football has a mass of 0.3 kg and is traveling at 26 m/s, and you and your skates have a mass of 90 kilograms, what is your speed after you throw the ball? Assume no friction. A: 0.087 m/s B: 7.9 m/s C: 87 m/s D: 9.8 m/s
Your friend is catching a falling basketball after it has passed through the basket. Her hands move straight down while catching the ball. It takes about 0.10 s for the player to lower her hands to stop the ball. Assume the mass of the ball is 0.60 kg, and that the ball has fallen a vertical distance of 1.2 m before reaching the player's hand. Determine the average force that her hands exert on the ball while catching it.

Hi please help with the following: After hitting a long fly ball that goes over the right fielder's head and lands in the outfield, the batter decides to keep going past second base and try for third base. The 59 kg player begins sliding 3.40 m from the base with a speed of 4.35 m/s. If the player comes to rest at third base, what was the coefficient of kinetic friction between the player and the ground?
