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 moving along the circular path with a speed v and its speed increases by g in one second.If the radius of the circular path be r ,then the net acceleration of the particle is?

A particle moving along the circular path with a speed v and its speed increases by g in one second. If the radius of the circular path be r, then the net acceleration of the particle is:

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 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)

A force exerts an impulse Ion a particle changing its speed from initial velocity u to final velocity 2u . The applied force and the initial velocity are oppositely oriented along the same line. The work done by the force is

A particle is moving along x-direction with a constant acceleration a. The particle starts from x=x_0 position with initial velocity u. We can define the position of the particle with time by the relation x=x_0+ut+(1)/(2)at^2 plot the position of the particle in relation with time is following situations (i) If initial position of the particle is on negativ x-axis, initial velocity is positive and acceleration is negative. (ii) If initial position is positive, initial velocity is negative and acceleration is positive.
