Two boxes of masses m, and me lie on a wedge and are connected by a massless cord going through a massless pulley, as shown in the figure. The angles of the inclined planes with respect to the horizontal are, respectively, Đa and eg. The coefficient of static friction between the boxes and the two planes is 4g. (a) Find formulas for the minimum and maximum values of ma/ma such that the two boxes remain stationary; also, find the critical value of u, such that box B will never slide down the incline. (b) Assuming ma/ma larger than the maximum value found in (a), and coefficient of kinetic friction Ag, find a formula for the acceleration of the two boxes in terms of the two angles, the two masses and the coefficient of kinetic friction. (c) For case b, find a formula for the tension force. This problem must be solved symbolically, no need to substitute numbers.

Help! An asteroid is heading towards us at 10 km/s. Scientists decide the best solution is to attach a rocket to the asteroid and fire it to change the trajectory of the asteroid. If the rocket is fired for 8 min, the scientists calculate that the new speed for the asteroid will be 21 km/s and its new trajectory will be at an angle of 25° to its original path. Part A In the process described above, what is the acceleration of the asteroid? Express your answers using two significant figures separated by a comma. Assume that the positive axis is in the direction of the initial motion of the asteroid. The final motion of the asteroid has components in the x and positive y directions only. ax ay = for Part A for Part A undo for Part A redo for Part A reset for Part A keyboard shortcuts for Part A help for Part A Review I Constants m/s2

Toy car W travels across a horizontal surface with an acceleration of aw after starting from rest. Toy car Z travels across the same surface toward car WW with an acceleration of az after starting from rest. Car W is separated from car Z by a distance d. Which of the following pairs of equations could be used to determine the location on the horizontal surface where the two cars will meet, and why?

Solve question no. 01 and show a clear and organized solution. Write also the GIVEN and REQUIRED. Thanks!!!
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°
