A 37.4 kg beam is attached to a wall with a hinge and its far end is supported by a cable such that the angle between the beam and the cable is 90o. If the beam is inclined at an angle of theta = 27.9o with respect to horizontal, what is the magnitude of the horizontal component of the force exerted by the hinge on the beam?

m1 = 1.6 kg block slides on a frictionless horizontal surface and is connected on one side to a spring (k = 45 N/m) as shown in the figure above. The other side is connected to the block m2 = 3.2 kg that hangs vertically. The system starts from rest with the spring unextended.
a) What is the maximum extension of the spring? (*Note: I have tried 0.7m but it doesn't work)
b) What is the speed of block m2 when the extension is 65 cm?2 AnswersPhysics9 months ago
