Speed and Average speed

STATEMENT - 1 : A particle is projected vertically upwards with speed v. Starting from initial point, its average velocity is less than average speed than average speed when particle is returning back to ground. and STATEMENT - 2 : When particle turns back, its displacement is less than distance covered.

The ratio of root mean square speed ,average speed and most probable speed for gas ?

The ratio between most prbable speed, average speed and root mean square speed is……

Suppose a container is evacuated to leave just one molecule of a gas in it. Let v_(mp) and v_(av) represent the most probable speed and the average speed of the gas, then

A car traveled 65% of the way from Towm A to Town B at an average speed of 65 mph. The car traveled at an average speed of v mph for the remaining part of the trip. The average speed for the entire trip was 50 mph. What is v is mph?

On the second leg of a certain journey, a person traveled at an average speed 50 percent greater than the average speed at which the person traveled the first leg of the journey, and for an amount of time 50 percent greater than the amount of time spent on the first leg of the journey. The person's average speed for the entire journey was what percent greater than the person's average speed on the first leg of the journey ?

A truck moves a distance of 50 km. It covers first half of the distance at speed of 200 m/s and second half at speed v. If average speed of truck is 100 m/s then value of v is

For gas at a temperature T the root-mean-square speed v_(rms) , the most probable speed v_(mp) , and the average speed v_(av) obey the relationship

Distinguish between average speed and average velocity.
