Question

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

Answer 1

here is your answer

given :

velocity = 50 m/s

time taken = 20 min. = 20×60 = 1200 seconds

to find : velocity at t = 2 min. = 2×60 = 120 seconds

solution :

distance travelled = velocity×time taken

distance travelled = 50×1200 = 60000 meter

now, velocity at t = 2 min. or 120 seconds

velocity = distance travelled/time taken

velocity = 60000/120

velocity = 500 m/s
