when it returns to the starting point?
A car is moving horizontally along a straight line with a uniform velocity of 25ms^−1. A projectile is to be fired from this car in such a way that it will return to it after it has moved 100m. The speed of the projection must be.

A particle starts from the origin with a velocity of 10ms^−1 and moves with a constant acceleration till the velocity increases to 50ms^−1. At that instant, the acceleration is suddenly reversed. What will be the velocity of the particle, when it returns to the starting point?
