A body starting with a velocity v returns to its initial position after t second with the same speed, along the same line. Acceleration of the particle is

A body starts with an initial velocity of 10ms-1 and is moving along a straight line with constant acceleration. When the velocity of the particle is 50ms- the acceleration is reversed in direction. The speed of the particle when it again reaches the starting point is

Three particles starts from origin at the same time with a velocity 2 ms^-1 along positive x-axis, the second with a velocity 6 ms^-1 along negative y-axis, Find the velocity of the third particle along x = y line so that the three particles may always lie in a straight line.

A particle is initially at rest. It starts moving with a constant acceleration, the speed of the particle in t seconds is 50m/s and after one second the speed becomes 75m/s. calculate the acceleration of the particle and distance covered in (t+1)^("th") second of its motion.

A particle strikes elastically with another particle with velocity V after collision its move with half the velocity in the same direction find the velocity of the second particle if it is initially at rest

A particle starts with an initial velocity u towards + x direction with an acceleration a after time t_(1) , it starts retarding with another acceleraation a' , comes to an instantaneous stop and returns. If reaches its initial position at time t_(2) . Draw the approximate time dependence plots for particle's displacement and velocity.

A body of mass ‘M’ collides against a wall with a velocity v and retraces its path with the same speed. The change in momentum is (take initial direction of velocity as positive)
