Two blocks are connected by a massless rope. The rope passes over an ideal (frictionless and massless) pulley such that one block with mass m1 = 12.25 kg is on a horizontal table and the other block with mass m2 = 7.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Use the coordinate system specified in the diagram. a.) Assuming friction forces are negligible, write an expression, using only the variables provided, for the acceleration that the block of mass m1 experiences in the x-direction. Your answer should involve the tension, T. b.) Under the same assumptions, write an expression for the acceleration, a2, the block of mass m2 experiences in the y-direction. Your answer should be in terms of the tension, T and m2. c.) Carefully consider how the accelerations a1 and a2 are related. Solve for the magnitude of the acceleration, a1, of the block of mass m1, in meters per square second. d.)Find the magnitude of the tension in the rope, T, in newtons.
A 13.0-kg bucket is lowered vertically by a rope in which there is 150 N of tension at a given instant. Part A What is the acceleration of the bucket? Express your answer using two significant figures.
please help me. double and triple check your answers, previous tutors got it wrong. this is a practice problem, not for a grade. i attached the question in one screenshot, and my previous incorrect answers as another. this is part c so what i got outta part A and B is the minimum value of the coefficent is 0.49 and the answer to part b which asked, As the snow begins to melt the coefficient of static friction decreases and the snow finally slips. Assuming that the distance from the chunk to the edge of the roof is 6.0 mm and the coefficient of kinetic friction is 0.17, calculate the speed of the snow chunk when it slides off the roof, is 5.8 m/s
Can someone please explain it to me ASAP?!!!
Please see the image provided for context and solve the following problem: Solve for and use the magnitude of the force of friction on Debbie and the tension in the rope to solve the problem. The bruin is hungrier than Sarita anticipated, and she decided she needs to pull harder, accelerating Debbie up the rocky slope. Sarita's rope can only manage a tension of 950N. What is the maximum acceleration Sarita can accomplish with this rope?
In the arrangement shown in the figure wedge of mass m moves towards the left with an acceleration a. All surfaces are smooth (i.e. frictionless). Draw a free body diagram. If the block falls freely then determine acceleration. Starting position Position at time t
Show transcribed image text a) Refer to Figure #1. A wagon is moving in a straight line with constant acceleration ax and its kinematics is measured with respect to inertial coordinates (X1, Y1). A ball inside the wagon is acted upon by a force F (components F7 and Fy) and gravity force Mg. The coordinate (x2. Y2) is moving with the wagon. Determine the acceleration of the ball measured in the (X2. Y2) coordinate frame. In other words, compute the acceleration of the ball relative to the wagon. (a) Answer: a(M/W)x = FX/M - ax; a(M/W)y = Fy/M - g

Consider a person serving a platter of hot food to their family who is gathered around a table. When holding theplatter, the person can choose how to hold the platter in front of them and would like compare the differences between position 1 and position 2 as shown below. In position 1, the shoulder is at 0 degrees while the elbow is at 90 degrees and in position 2, the arm is flexed as shown. a.) Consider the elbow joint and draw free body diagrams for each of the positions shown, including gravitational forces (consider the weight of the combined forearm and hand), elbow flexor forces, and the joint contact force. b.) Use the information provided below to solve for the magnitude of the elbow flexor force (in Newtons) for positions 1 and 2, the magnitude of the joint contact force (in Newtons), and the angle that the joint contact force makes with respect to the horizontal axis. • The platter of food weighs 7 lbs; the person weighs 175 lbs, and the person is 5’8” tall. • θ = 130…
I Review Part A A crate, seen from above, is pulled with three ropes that have the tensions shown in (Figure 1). Tension is a vector directed along the rope, measured in newtons (abbreviated N). Assume T1 = 50 N, T2 = 55 N, and T3 = 65 N. Suppose the three ropes are replaced with a single rope that has exactly the same effect on the crate. What is the tension in this rope? Enter the x and y components of the tension in newtons separated by a comma. nV ΑΣφ Te, Ty = Submit Request Answer Figure 1 of 1 Provide Feedback Next y 45° 30°
