Aperson began running due east and covered 15 km in 2.0 hr. what is the average velocity of the person? (hint: v = d/t) show all your work!

d = total displacement of the person running due east = 15 km

t = time taken by the person to travel the given distance due east = 2.0 hr

v = average velocity of the person in east direction = ?

average velocity is the ratio of total displacement to total time taken. hence

average velocity = total displacement/total time

v = d/t

inserting the values

v = 15 km/2.0 hr

v = 7.50 km/hr

c) up is the direction the magnetic force is acting on the charge.
