Answer:
The average velocity is 2 m/s.
Explanation:
The velocity of the particle is the time derivative of its position
Now the average from and
is
Thus, the average velocity is 2 m/s.
Answer:
Explanation:
Since, Alex is at rest. Therefore, the speed measured by him will be the absolute speed of car P. Therefore, taking easterly direction as positive:
And the absolute velocity of Barbara's Car is given as:
Now, for the velocity of Car p with respect to the velocity of Barbara's Car can be given s follows:
