Question

A shop sign weighing 205 N is supported by a uniform 170-N beam as shown in the figure (Figure.1). Find the magnitude of the tension in the guy wire. Find the horizontal component of the force exerted by the hinge on the beam. To the right is the positive direction. Agent Arlene devised the following method of measuring the muzzle velocity of a rifle. She fires a bullet into a 4.200-kg wooden block resting on a smooth surface, and attached to a spring of spring constant k = 137.0 N/m. The bullet, whose mass is 7.900 g, remains embedded in the wooden block. She measures the maximum distance that the block compresses the spring to be 9.460 cm (Figure 1) What is the speed v of the bullet? Express your answer using four significant figures.
