A body starting with an initial velocity of 5 m//s , moves with a uniform acceleration of 2 m//s^(2) . After some time it attains a velocity of 13 m//s . Find the distance covered by the body during this period.

A body starting with an initial velocity of 4 m//s , moves with a uniform acceleration of 0.5 m//s^(2) . After some time its velocity becomes 6 m//s . Calculate the time taken by the body to attain this velocity and the distance covered by it during this time interval.

A particle of mass m is projected from the ground with an initial speed u_0 at an angle alpha with the horizontal. At the highest point of its trajectory, it makes a completely inelastic collision with another identical particle, which was thrown vertically upward from the ground with the same initial speed u_0. The angle that the composite system makes with the horizontal immediately after the collision is
