The speed of light can be found by measuring the time interval required for a laser beam to travel from the Earth, reflect from the panel, and return to the Earth. Assume this interval is measured to be 2.51 s at a station where the Moon is at the zenith and take the center-to-center distance from the Earth to the Moon to be equal to 3.84 × 10% m.

SHOW THE SOLUTION NEATLY A surveyor is walking at the rate of 4 ft/sec along the diameter of a circular courtyard. A light at one end of a diameter perpendicular to her path casts a shadow on the circular wall. How fast is the shadow moving along the wall when her distance to the center of the courtyard is r/2? a. 4 ft/sec b. 6 ft/sec c. 2 ft/sec d. 9 ft/sec

A small vertical mirror hangs on the wall,1.40 m above the floor.

You’re driving to Carey Lake to get the last rays of summer when the light turns red at the Umtanumintersection. You just pass Koletty’s, so you know you know you are exactly 110 m from the intersection.If your reaction time is half a second and you were driving 20 m/s before the light changed, whatacceleration will bring you to a stop right at the edge of the intersection? [-2 m/s2]
