Pmoves with negligible friction in the slot and is restrained by the inextensible cable BP. 0.3BPm. Please note that OBP is an isosceles triangle, and 20.3cosrm. The arm starts from rest at θ= 0°, and moves with constant angular acceleration = 4 rad/sec2. Write an expression for the tension in the cable as a function of t and only, for the interval of 0 t 0.5 sec. Assume the slot is long enough to allow the full motion of the slider. Not to scaler

Problem 2.Two particles A and B strike each other as shown. Their masses are 5Amkgand 8Bmkg. Just before collision, ˆ10Amvisand ˆ7Bmvis . The coefficient of restitution is 0.4e. Determine the velocities of both particles immediately after the collision, expressing components in the directions of the common normal and common tangent. AB45°

Problem 3.A particle Ais released on a 40° slope. The coefficient of friction along the slope is μs= μd= 0.2. The particle eventually contacts a massless pad attached to a linear spring having a spring constant of k= 150 N/mm. What is the maximum compression of the spring? 5 m

Problem 4.Shown is the side view of a massless plate of length L= 40 cm with a bar of mass M= 10 kg attached to the end, supported at the top by a frictionless, horizontal hinge. A horizontal jet of water is directed at the plate and strikes it at a vertical distance dfrom the center of the hinge. If d= 8.0cm, and the jet velocity and mass flow rate are v= 32m/s and m'= 12 kg/s, calculate the angle θthat the plate forms with the vertical, once a steady state position has been established. Assume the fluid velocity vector is coincident with the hinge as the fluid leaves contact with the plate. M
