Balintad ` Distance and DisplacementProblem:An object moves from point A to point B to point C, then back to point B and then to point C along the line shown in the figure below.a) Find the distance covered by the moving object.b) Find the magnitude and direction of the displacement of the object.Solution:a) distance = AB + BC + CB + BC = 5 + 4 + 4 + 4 = 17 kmb) The magnitude of the displacement is equal to the distance between the final point C and the initial point A = AC = 9 kmThe direction of the displacement is the direction of the ray AB. ` SPEED AND VELOCITY1. Problem:A man walks 7 km in 2 hours and 2 km in 1 hour in the same direction.a) What is the man's average speed for the whole journey?b) What is the man's average velocity for the whole journey?Solution:a)average speed = distancetime=7 km + 2 km2 hours + 1 hour=9 km3 hours= 3 km/hb)average velocity = displacementtime=7 km + 2 km2 hours + 1 hour=9 km3 hours= 3 km/h2. Problem:A man walks 7 km East in 2 hours and then 2.5 km West in 1 hour.a) What is the man's average speed for the whole journey?b) What is the man's average velocity for the whole journey?Solution:a)average speed = distancetime=7 km + 2.5 km2 hours + 1 hour=9.5 km3 hours= 3.2 km/h (approximat
