On a trip to the store around the block a bike rider goes 75 m toward the West and 75 m toward the North at a
constant speed of 1.5 m/s. What is the magnitude of the average velocity? (1 point)

The average velocity of the rider over the course of his trip to the store is 1.0607m/s.

By definition;

  • Velocity = Displacement/Time

The path of the bike rider towards the west and then towards the north signifies a right angle path.

As such the displacement, s can be given as;

s = √(75² + 75²).

Therefore, the displacement, s = 106.07m

The time taken to cover the 75meters in each direction, t = distance/speed = 150/1.5

Therefore, the time taken = 100s.

The average velocity, v = displacement/time

v = 106.07/100

Therefore, Average velocity, v = 1.0607m/s.
