A car moves with speed `v_(1)` upto `(t)/(3)` time and then with speed `v_(2)` upto next `(2t)/(3)` time.Path is straight line.What is the average speed of car

A particle travels along a straight line. It covers halg the distance with a speed (v). The remaining part of the distance was covere with speed v_(1) for half the time and with speed v_(2) for the other half the time . Find the average speed of the particle over the entire motion.

If a car covers (2)/(3) of the total distance with speed nu_(1) and (3)/(5) distance with speed v, then average speed is

A person travels along a straight road for the first (t)/(3) time with a speed v_(1) and for next (2t)/(3) time with a speed v_(2) . Then the mean speed v is given by

A particle moves with a velocity v(t)= (1/2)kt^(2) along a straight line . Find the average speed of the particle in a time t.

09A body moving in a straight line covers half the distance with a speed V the remaining part of the distance was covered with a speed V for half the time and with a speed V for the other half of the time.What is the average speed of the body?

A car starts from rest and moves with uniform acceleration for time t then it moves with uniform speed of 60 km/h for time 3t and comes to rest. Find the average speed of car in its total journey.

A particle move with velocity v_(1) for time t_(1) and v_(2) for time t_(2) along a straight line. The magntidue of its average acceleration is

A particle moves in a straight line from A to B (a) for the first half of distance with speed v_(1) and the next half of distance with speed v_(2) . (b) for the first one-third distance with speed v_(1) and the next two-third distance with speed v_(2) . (c ) for the first one-fourth distance with speed v_(0) , the next half of distance with speed 2v_(0) and the last one-fourth distance with speed 3v_(0) . Find the average speed in each case.

A body moves speed V_1 for distance L and then with speed V_2 for distance 2L. The average speed for the motion is
