Concept explainers
(a)
To find: The exact times at which the particle collide.
(a)
Answer to Problem 61E
The particle collide at
Explanation of Solution
Given Data:
The path of the two particle for the time
Calculation:
Consider that the particle collide when the components of the position vectors are equal then by equating the
Thus, the particle collide at
(b)
To find: The find the direction of the motion of each particle at the time of the collision.
(b)
Answer to Problem 61E
The direction of the unit vector is
Explanation of Solution
Consider that at time
Consider that at
For the second particle the velocity vector is,
Consider that at
Then, the magnitude is
Thus, the direction of the unit vector is
