A body of mass M at rest explodes into three pieces, two of which of mass M//4 each are thrown off in perpendicular directions eith velocities of 3m//s and 4m//s respectively. The third piece will be thrown off with a velocity of

Two masses nm and m , start simultaneously from the intersection of two straight lines with velocities v and nv respectively. It is observed that the path of their centre of mass is a straight line bisecting the angle between the given straight lines. Find the magnitude of the velocity of centre of mass. [Here theta= angle between the lines]

The distance of the two planets from the Sun are 10^(13)m and 10^(12) m , respectively. Find the ratio of time periods of the two planets.

Two particles are projected from a tower horizontally in opposite directions with velocities 10 m//s and 20 m//s . Find the time when their velocity vectors are mutually perpendicular. Take g=10m//s^2 .

Two particles P and Q simultaneously start moving from point A with velocities 15 m//s and 20 m//s respectively. The two particles move with acceleration equal in magnitude but opposite in direction. When P overtakes Q at point B then its velocity is 30 m//s , the velocity of Q at point B will be

Two particles are simultaneously thrown from the top of two towards as shown. Their velocities are 2ms^(-1) and 14ms^(-1) . Horizontal and vertical separations between these particles are 22 m and 9 m respectively. Then the minimum separation between the particles in the process of their motion in meters is (g=10ms^(-2))
