1. A scientist measures the distance to a mountain by shining a laser at a sensor held by her -5 seconds after assistant, who is standing on the mountain. If the laser pulse is detected 3.2 x 10 it was emitted, calculate the distance between the scientist and the mountain. (Give answer in meters) 80 F3 D00 D00A F5 F7 & * 4 5 9. 7 8
