Question

3. A particle P is moving with a constant speed of 6m/s in a direction 2i - j - 2k. When t = 0, is at a point whose position vector is 3i+4j-7k. Find the position vector of the particle P after 4 seconds. ​

Answer 1

Answer:

19i - 4j - 23k

Explanation:

First find Unit vector in the given direction.

Then velocity.

now find total displacement.

So, Displacement is change in postion.

we have initial position and total displacement..so we can find final position.
