Car B turns such that its speed is increased by (Q.)=(0.5e)m/s, where t is in seconds. If the car starts from rest when =0°, determine the magnitude of its velocity and acceleration when the arm AB rotates =30°. Neglect the size of the car. (Note: using tangent and normal components to solve this problem)
Do not round intermediate calculations; however, for display purposes report intermediate steps rounded to four significant figures. Give your final answer(s) to four significant figures. For the slider-crank mechanism shown, let R 23 mm, L 75 mm, and H 35 mm. If θ 1,700 rpm, determine the angular velocity of the connecting rod AB and the speed ofthe slider B for θ-90°.
