A rotating beacon is located 6 ft from a wall The distance f

A rotating beacon is located 6 ft from a wall. The distance from the beacon to the point on the wall where the beacon is aimed is given by a = 6|sec 2pi t|, where t is time measured in seconds since the beacon started rotating. Find a for t = 0.3 seconds. Round your answer to the nearest hundredth. 19.417 ft -19.417 ft 14.812 ft 10.208 ft

Solution

a=6 I sec2pi*t I

t=0.3 secs

a=6 I sec 2pi*.3 I

a=6 I sec 108 I = 6   I -3.23607 I= 6*3.23607 = 19.417 ft
