Refer `Q. 143`, What is the average velocity of the particle from `4 s` to `8 s` ?

A particle is moving with uniform acceleration along a straight line. The average velocity of the particle from P to Q is 8ms^(–1) and that Q to S is 12ms^(–1) . If QS = PQ, then the average velocity from P to S is

A particle is moving with uniform acceleration along a straight line ABC, where AB= BC. The average velocity of the particle from A to B is 10 m/s and from B to C is 15 m/s. The average velocity for the whole journey from A to C in m/s is

Five particles have speeds 1, 2, 3, 4, 5 m/s. The average velocity of the particles is (in m/s)

The intantaneous coordinates of a particle are x= (8t-1)m and y=(4t^(2))m . Calculate (i) the average velocity of the particle during time interval from t =2s to t=4s (ii) the instantaneous velocity of the particle at t = 2s .

A particle moves for 20 s with velocity 3 m//s and then moves with velocity 4 m//s for another 20 s and finally moves with velocity 5 m//s for next 20 s. What is the average velocity of the particle ?

A particle moves in a straight line for 20 seconds with velocity 3 m/s and then moves with velocity 4 m/s for another 20 seconds and finally moves with velocity 5 m/s for next 20 seconds. What is the average velocity of the particle ?

Refer Q.141 find the displacement of the particle after 3 s .

A particle moves in straight line in same direction for 20 seconds with velocity 3 m//s and the moves with velocity 4 m//s for another 20 sec and finally moves with velocity 5 m//s for next 20 seconds. What is the average velocity of the particle?
