Question1

The magnitude of four displacement vectors shown in the drawing are A = 16.0 m, B = 11.0 m, C = 12.0 m, and D = 26.0 m. conclude the magnitude and directional angle for the resultant that occurs as these vectors are added together.

Question2

Solar-powered car as a function of time. The driver accelerates from a stop sign, cruises for 20 {rm s} at a constant speed of 60 {rm{ km/h}}, and then brakes to come to a stop 40 {rm s} after leaving the stop sign. Calculate an average acceleration during the time interval t = 0 to t = 10{rm{s}}.

Question3

You are driving to the grocery store at 20 {rm m/s}. You are 110 {rm m} from an intersection when the traffic light turns red. Suppose that your reaction time is 0.50 {rm s} and that your car brakes with constant acceleration. What acceleration will convey you to rest right at the intersection? How long does it take you to stop after the light turns red?
