If the coefficient of static friction between the block and the bowl is μs and the block is slowly repositioned at different points down the surface of the bowl, at what angle measured from the vertical will the block begin to slide? Write your answer in terms of the mass, m; the gravitational acceleration on Earth, g; and the coefficient of static friction, μs. (Assume the +y axis is vertically upward.)
- A concrete block of mass 225 kg hangs from the end of the uniform strut of mass 45.0kg.A bag is gently pushed off the top of a wall at A and swings in a vertical plane at the end of a rope of length I. Determine the angle 0 for which the rope will break, knowing that it can withstand a maximum tension equal to twice the weight of the bag.Shown to the right is a block of mass m resting on a frictionless ramp inclined at an angle to the horizontal. The block is held by a spring that is stretched a distance d after the block is attached to it. E k= e wwwwww ▷ A Write an equation for the force constant of the spring in terms of the variables from the problem statement (m, 0, and d). Use g for the gravitational constant.
- Needs Complete typed solution with 100 % accuracy.A force F of 36N acts on a box in the direction of the vector OP, where P (-5,7,–3) and O(0,0,0). Express the force as a vector. F = help (vectors) Find the angle between force F and the xy-plane. Answer in radians. help (angles)Problem 1: A 2.80kg block is placed on a rough (us=0.540) incline that makes an angle of 52.0° with respect to the horizontal. A pushing force horizontal to the ground is applied to the top of the block (This would make the force have an angle of 52.0° below the surface of the inclined plane, up the plane) to make the block stationary on the plane. What is the minimum pushing force needed to keep the block stationary on the plane? (10 points)
- Please circle answersPART A) What is the maximum force that can be applied to a bone whose minimum cross-sectional area is 3.0cm^2? (This is approximately the cross-sectional area of a tibia, or shin bone, at its narrowest point.) Express your answer using two significant figures. PART B) Estimate the maximum height from which a 70kg man could jump and not fracture the tibia. Take the time between when he first touches the floor and when he has stopped to be 0.006s, and assume that the stress is distributed equally between his legs. Express your answer using two significant figures. Thank you!!!I was given this problem, and I don't really know what to do about the fact that the normal force doesn't equal the weight for this problem. How am I supposed to find the kinetic friction coefficient now? A box of mass 2,463g is on level ground being pulled by a force of 6.41N at angle 47.2 above horizontal. If the block is moving with a constant velocity, what is the kinetic friction coefficient? (Hint: the normal force does not always equal the weight; it does not in this case.)
