A point travelling along a straight line, traversedone third the dista

1.	A point travelling along a straight line, traversedone third the distance with a velocity vo. Theremaining part of the distance was covered withvelocity v, for half the time and with velocity v, forthe other half of the time. Find the mean velocity ofthe point averaged over the whole time of motion.
Answer» Answer: 6v0v1v2/(2V0 + V1 + v2) Explanation: Avg. velocity = total DISTANCE /total time = d/(d/3v0 + d/6v1 +d/6v2) = 1/(1/3v0 + 1/6v1 +1/6v2) = 3/(V0 + 0.5v1 + 0.5v2) = 6v0v1v2/(2v0 + v1 + v2)

Answer:

6v0v1v2/(2V0 + V1 + v2)

Explanation:

Avg. velocity = total DISTANCE /total time

= d/(d/3v0 + d/6v1 +d/6v2)

= 1/(1/3v0 + 1/6v1 +1/6v2)

= 3/(V0 + 0.5v1 + 0.5v2)

= 6v0v1v2/(2v0 + v1 + v2)
