You are driving in one direction on a long straight road. You drive in the positive direction at 126 km/h for 30.0 minutes, at which time you see a police car with someone pulled over presumably for speeding. You then drive in the same direction at one hundred km/h for 45 minutes. (a) How far did you drive? b) What was your average velocity in kilometers per hour?
Draw the position vs. time graph for this problem

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
