Next, imagine the rather than sliding down the hill, the skier holds onto a rope that is connected to a tree at the top of the hill, and that the force of the rope holds the skier in place. How would you modify your force diagram now? Hint: The rope is parallel to the surface of the hill. Show that the net force is zero, again by using the parallelogram rule to show that any 2 forces add up to exactly cancel the 3rd force. Note that tension force is always along the direction of the rope but is not drawn equal to the length of the rope. What must be true for an object in equilibrium is that vector sum of the forces in any and every direction must equal zero. Though, we only need to show that along our chosen coordinate axes. Here it is okay to use the "usual" x- and y- directions

Astronauts in orbit are apparently weightless. This means that a clever method of measuring the mass of astronauts is needed to monitor their mass gains or losses, and adjust their diet. One way to do this is to exert a known force on an astronaut and measure the acceleration produced. Suppose a net external force of 50.0 N is exerted, and an astronaut’s acceleration is measured to be 0.893m/s2 . (a) Calculate her mass. (b) By exerting a force on the astronaut, the vehicle in which she orbits experiences an equal and opposite force. Use this knowledge to find an equation for the acceleration of the system (astronaut and spaceship) that would be measured by a nearby observer. (c) Discuss how this would affect the measurement of the astronaut’s acceleration. Propose a method by which recoil of the vehicle is avoided.
A history book is lying on top of a physics book on a desk, as shown below a free-body diagram is also shown. The history and physics books weigh 14 N and 18 N, respectively. Identify each force on each book with a double subscript notation (for instance, the contact force of the history book pressing against physics book can be described as F HP), and determine the value of each of these forces, explaining the process used.
Two boxes, A and B, are at rest Box A is on level ground, while box B rests on an inclined plane tilted at angle with the horizontal. (a) Write expressions for the normal force acting on each block (b) Compare the two forces; that is, tell which one is larger or whether they are equal in magnitude. (c) If the angle of incline is 10 , which force is greater?
A 0.0502-kg pair of fuzzy dice is attached to the rearview mirror of a car by a short string. The car accelerates at constant rate, and the dice hang at an angle of 3.20 from the vertical because of the car’s acceleration. What is the magnitude of the acceleration of the car?
Consider the 52.0-kg mountain climber shown below. (a) Find the tension in the rope and the force that the mountain climber must exert with her feet on the vertical rock face to remain stationary. Assume that the force is exerted parallel to her legs. Also, assume negligible force exerted by her arms. (b) What is the minimum coefficient of friction between her shoes and the cliff?

Can you help me pleas . Determine the smallest force the man must exert on the rope in order to move the (80+b)kg crate shown in figure (4). Also, what is the angle at this moment? The coefficient of static friction between the crate and the floor is us = 0.3 . (b = 15)
Hannah and Andreas housemates, David and Stephanie, disagree with the move and want to prevent the relocation. Their combined force FDs must be equal and opposite to that of FHA. What is the magnitude in newtons of the force FDS that will prevent the relocation?
where is the free body diagram? pls help
suppose twoo children push horizontally but in exactly opposite directions on a third child on a sled. The first child exters a force of 75N, the second a force of 98N, kinetic friction is 5.5N and the mass of the third child pus the sled is 21kg.Using a coordinate system where the second child is pushing in the postive direction, calculate the accelteration in m/s2.
The system shown is at rest. Box 2 weighs 61N. Determine all unknowns, neglecting friction in the pulley and the weight of the knot and each string. How much does box 1 weigh? How much does box 3 weigh? I know that T1cos(θ) = T2cos(θ)T1sin(θ) + T2sin(θ) = The Weight of Box 2 But how do I find T1 and T2? ( The Hyp's)
