Question

This object was moving at a velocity of 1.0 m/s east at the end of 4.0 seconds. Determine the average and instantaneous velocities in m/s at 6.0 seconds.

Average = 1.0 m/s east; instantaneous = 4.0 m/s east
Average = 4.0 m/s east; instantaneous = 6.0 m/s east
Average = 0.67 m/s east; instantaneous = 0 m/s
Average = 1.0 m/s east; instantaneous = 0 m/s

Answer 1

Average = 0.67 m/s east; instantaneous = 0 m/s

Answer 2

The average and instantaneous velocities in m/s at 8.0 seconds would be 0.5 m/s and 0 m/s respectively, therefore the correct answer is option D.

What is Velocity?

The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.

As given in the problem, this object was moving at a velocity of 1.0 m/s east at the end of 4.0 seconds.

The average velocity of the object = ( 4 - 0 ) / (8 -0)

The instantaneous velocity of the object = 0 m/s

Thus, the average and instantaneous velocities in m/s at 8.0 seconds would be 0.5 m/s and 0 m/s respectively, therefore the correct answer is option D.
