Answer:
Explanation:
(A) What is the elapsed time?
t = 6.5 + 3.0 + .05 = 10 hr
(B) What is the total distance traveled?
d = 250 + 155 + 32 = 437 km
(C) What is the total displacement?
d = √((250 - 32)² + 155²) = 267.48644... = 267 km
as displacement is a vector, we also need a direction
θ = arctan((250 - 32) / 155) = 54.6° S of W
(D) What is the average speed for the trip?
437/10 = 43.7 km/hr
(E) What is the average velocity for the trip
267/10 = 26.7 km/hr 54.6° S of W
