Predict/Calculate Illinois Jones is being pulled from a snake pit with a rope that breaks if the tension in it exceeds 755 N. (a) If Illinois Jones has a mass of 70.0 kg and the snake pit is 3.40 m deep, what is the minimum time that is required to pull our intrepid explorer from the pit? (b) Explain why the rope breaks if Jones is pulled from the pit in less time than that calculated in part (a).

no air resistance, g=9.81 mls^2 mB=2450 goes up ramp, and the coefficient of kinetic friction between mass b and the ramp is 0.6. The ramp makes an angle of 63 degrees  a counterweight is used to raise stone B by tying it to a second mass MA. The coefficient of friction for mA as it slides down the shaft is 0.4 pitched at an angle of 13 degrees.  question- draw a body diagram for mass B and write 2 equations for the forces in x and y direction.

If the bird's mass is 82 g, what is the maximum net vertical force exerted on the bird?Can someone help me solve these two questions? I thought it was a direct plug into f=ma.

9) Two blocks are positioned on surfaces, each inclined at the same angle of 48.2 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 2.62 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.250. Assume static friction has been overcome and that everything can slide. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2? Question 9 options:   1.12 kg   6.55 kg   4.11 kg   2.49 kg   10) Two blocks are positioned on surfaces, each inclined at the same angle of 50.3 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black…

The coefficient of static friction at all contacting surfaces is μ. The blocks are identical and weigh W. Determine the angle at which the blocks begin to slide. Answer: 0 = tan=¹ (5μ) A B 0 I

A bowling ball of mass m = 2.1 kg drops from a height h = 11 m. A semi-circular tube of radius r = 8.2 m rests centered on a scale.  1) Write an expression for the reading of the scale when the bowling ball is at its lowest point, in terms of the variables in the problem statement.  2) What does the scale read, in newtons?

e) Clearly, there is a force of gravity on the space station and everything inside of it. Yet, the apparent weight of an object aboard the space station is roughly zero, i.e. objects float around relative to the space station as if there is no force of gravity. Explain why objects at the space station appear "weightless", in 1 or 2 sentences. We talked about this in lecture. Nothing too complicated about this.
