Question

A particle moves with a uniform velocity 50m/s for 20min. what is the velocity of particle at t=2min

Answer 1

Given in your question, velocity is uniform, meaning that it will remain the same throughout its motion. Hence if it was 50m/s for 20 min, it will also be 50m/s for 2 min.

Uniform velocity means the velocity is the same

Answer 2

Uniform velocity: Velocity doesn’t change with time.

Particle is moving with uniform velocity of 50 m/s for 20 minutes. It means for entire 20 minutes it’s velocity is 50 m/s.

∴ Velocity after 2 minutes is also 50 m/s
