Question

A particle moves along an x axis . Does the kinetic energy of the particle increase decrease or remain same if the particle velocity change (a) from -3m/s to -2m/s and (b) from -2m/s to 2m/s (c) in each situation is the work done on the particle positive negative or zero​

Answer 1

a. decrease

b. remains same

c. work done on particle is positive

Answer 2

Answer:

Explanation:

In each situation the particle doing work along the x axis at origin to negative infinity or positive infinity on at the increasing or decreasing acceleration at the condition when velocity changes.
