Children playing pirates have suspended a uniform wooden plank with mass M = 13.4 kg, length ℓ = 2.40 m, and angle θ = 35.0°, as shown in the figure. Sophia, with a mass of m = 21.6 kg, is made to "walk the plank" and is d = 1.5 m from reaching the end of the plank. What is the tension acting on the rope at the end (i.e value of F3)?
The tension is growing!Context At your summer job, your supervisor wants to test your physics skills. A new winch (a cable driven by a motor) is to be used to hoist loads up an inclined ramp. Your supervisor is worried about the packages arriving too quickly at the top of the ramp. Constraints The inclined ramp is made up of small cylinders that are free to rotate: there is no friction between the ramp and the load.The angle theta of the ramp from the horizontal is known.The winch cable exerts a known force.The cable is oriented at an angle a from the horizontal.The charge, initially immobile, has a known mass.The length of the ramp is known. Schematization Draw a diagram of the object that interests us. Draw your x and y axes. Draw and name each force experienced by the object that interests us. Modelization Build a model to calculate the final speed of the load as it arrives at the top of the ramp, given the known parameters. Then test your model with the following values: Ramp…
Understanding the details of timing and forces in motion can improve the performance of athletes, including dancers. Consider the forces involved in a ballet jump called a sauté demi plié. P9.84a shows the sequence of moves in the jump. The dancer starts upright, then quickly bends her knees, moving downward. After she reaches the bottom of this dip, she extends her legs, pushing herself upward. After this upward push, she leaves the ground, beginning a short period of time in the air. P9.84b is a slightly idealized graph of the net force on a 42 kg dancer executing this move. The sauté demi plié begins with a phase in which the net force on the dancer is negative. During this phase of the jump,A. The normal force of the floor on her is zero.B. The normal force of the floor on her is less than her weight but greater than zero.C. The normal force of the floor on her is equal to her weight.D. The normal force of the floor on her is greater than her weight.
A tightrope walker is walking between two buildings holding a pole with length L = 16.5 m, and mass mp 17.5 kg. The daredevil grips the pole with each hand a distance d = 0.530 m from the center of the pole. A bird of mass - 525 g lands on the very end of the left-hand side of the pole. Assuming the daredevil applies upward forces with the left X4 and right hands in a direction perpendicular to the pole, what magnitude of force Fjeft and Fright must the left and right hand exert to counteract the torque of the bird?

8. A fisher slowly lifts a fish with a 6 m long fishing-rod, the mass of which 0.5 kg. One hand of the fisher holds grip at the end of the rod with a force 200 N, the other at a distance X from the end with a force 150 N. Find distance X and mass of the fish. Sketch the force diagram. Assume that the rod is a cylinder with uniform distribution of mass over its length.

Consider the woman doing push-ups in the figure. She has a mass of 49.2 kg, and the distance from her feet to her center of mass is 0.96 m, while the distance from her feet to her hands is 1.75m. a. What force in newtons should the woman in the figure exert on the floor with each hand to do a push-up? Assume that she moves up at a constant speed. b. The triceps muscle at the back of her upper arm has an effective lever arm of 1.95 cm, and she exerts force on the floor at a horizontal distance of 15.5 cm from the elbow joint. Calculate the magnitude of the force in newtons for each triceps muscle. c. How much work in joules does she do if her center of mass rises 0.27 m? d. What is her useful power output, in watts, if she does 25 pushups in one minute? For the sake of simplicity, ignore any power used by her muscles lowering her body during each pushup.
