Question

10. The pendulum of a clock swings through an angle of 2.5 radians as its tip travels through an arc of 50 centimeters. Find the length of the pendulum, in centimeters. 1. A student attaches one end of a rope to a wall at a fixed oint 3 feet above the ground, as shown in the companying diagram, and moves the other end of the pe up and down, producing a wave described by the uation y a sinbx+d. The range of the rope's height ove the ground is between 1 and 5 feet. The period of the ve is 4 π . Write the equation that represents this wave. 3 ft 3 1

Distance traveled d= r×theta
theta = 2.5 rad
r = d/theta = 50/2.5 = 20 cm
Length of the pendulum = 20 cm
