Question

A particle goes from A to B with the speed of 54 km/hr and returns back with the speed of 5 m/s. Calculate the average speed and average velocity of the particle. ​

Answer 1

Answer:

Explanation:

v from a to b = 54 * 5/18 = 15 m/s

∴average speed (v) = 2v₁v₂/(v₁+v₂)

= 2(15)(5)/(15+5)

= 7.5 m/s

average velocity (v') =( v₁ + v₂) / 2

= (15+5)/2 = 20/2 = 10 m/s

Answer 2

Answer:

The average velocity= 10 m/s....
