Question

Q1) Calculate the tensions in the three wires, if the mass hanging from wire C' is 150 kg. The wire A makes an angle 200 with the horizontal, and the wire B makes 60° with the horizontal. C is vertical. A 600 C Given that mi= 5.00 kg and m2 3.00 and the coefficient of kinetic friction Hk 0.25, calculate the acceleration of the block mi. After how much time would the speed of m2 be 9.00 m/s, if the system starts form rest? (6 points for drawing a good FBD) Q2) тy т2
