A particle is moving on a straight line with constant retardation of 1 m//s^(2) . Its initial velocity is 10 m//s .

A particle moves for 1 minute with a velocity of 15 m/s and moves for 0.5 minute with a velocity of 10 m/s. the average speed of particle is

A particle moving in a straight line covers half the distance with speed of 3 m//s . The other half of the distance is covered in two equal time intervals with speed of 4.5 m//s and 7.5 m//s respectively. The average speed of the particle during this motion is :

A particle travels half of the time with constant speed 2 m//s, In remaining half of the time it travels, 1/4 th distance with constant speed of 4 m//s and 3/4 th distance with 6 m//s. Find average speed during the complete journey.
