Question

Velocity of a particle is v=(2hat i + 3hat j - 4hat k) m//s and its acceleration is zero. State whether it is 1-D, 2-D or 3-D motion?

Answer 1

Answer:

Answer is 1-D you have to practice this question many times that i already did then you will be able to get the answer of this question.

Answer 2

Therefore the particle is having one dimensional motion.

Option (A) is correct.

Explanation:

We are given that:

Velocity of the particle =  2i + 3 j + 4 k

Acceleration "a" = 0 m/s^2

Solution:

Since acceleration is zero therefore it is uniform motion or motion in  a straight line. So, it is one dimensional motion.

Therefore the particle is having one dimensional motion.
