A Particle Moves East at Constant Velocity for a Time

question 8

Multiple Choice

A particle moves east at constant velocity for a time interval t. It then moves north at a constant velocity, with the same speed as before, for another time interval t Finally it moves east again with the original velocity. At the instant an additional time interval t has elapsed, which of the following are true about the average velocity and the average acceleration for the motion described?

• A) The average velocity is and the average acceleration is zero.
• B) The average velocity is and the average acceleration is not zero.
• C) The average velocity is not and the average acceleration is zero.
• D) The average velocity is not and the average acceleration is not zero.
