A sprinter of mass 67 kg starts a race with an acceleration of 4.3 m/s2. What is the magnitude of the net force on her? Include units as appropriate. Fnet =Two teams of nine members each engage in a tug of wart The first has an average mass per member of 67 kg and exerts an average force of 1320N horizontally. The second has an average mass per member of 73 kg and exerts an average force of 1365 N horizontally. Treat the mass of the rope to be negligible and the rope to be inextensible. Include units as appropriate below (a) What is the magnitude of the acceleration of each team? a: (b) What is the tension in the section of rope between the two teams? (It is helpful to sketch and analyze a free body diagram for each team.) T: The WeBWorK Project Home asgmt wk05 FALL2023: Problem 3 (1 point) A nurse pushes a cart by applying a force on the handle at a downward angle of 40" below the horizontal The loaded cart has a mass of 28.0 kg, and the force of friction between the cart and the ground is 60 N. What magnitude of force is needed for him to push the cart at a constant velocity? Include units as appropriate. F'IPP: Two children pull a third child on a saucer sled as shown in the figure below by applying forces F1 : 12 N and F2 : 8 N at angles a : 45 and = 30. What is the acceleration of the 49 kg sled and child system? Note that the direction of the acceleration, and hence the direction of the frictional force, is not given Its direction should be given counterclockwise from the positive horizontal axis. Include units as appropriate below. a = , angle = in compass direction Consider the mass of the baby being weighed in the following figure Treat the masses of the cords to be negligible. Include units as appropriate below. Nev/Ions (N) (a) what is the mass of the child and sling if a scale reading of 57N is observed? m = (b) What is the tension T1 in the cord attaching the baby to the scale? T1 = (c) What is the tension T2 in the cord attaching the scale to the ceiling if the scale has a mass of 053 kg? T2 =
