Two particles move in a uniform gravitational field with an acceleration g. At the intial moment the particles were located at one point and moved with velocity v_(1)=1" "ms^(-1)" and "v_(2)=4" "ms^(-1) horizontally in opposite directions. Find the time interval after their velocity vectors become mutually perpendicular

A stationary partical explodes into two partical of a masses m_(1) and m_(2) which move in opposite direction with velocities v_(1) and v_(2) . The ratio of their kinetic energies E_(1)//E_(2) is

Three block 1, 2 and 3 are arranged as shown in the figure. The velocities of the blockes v_(1) , v_(2) and v_(3) are shown in the figure. What is the relationship between v_(1) , v_(2) and v_(3) ?

A block A is placed over a long rough plank B of same mass shown below. The plank is placed over a smooth horizontal surface. At time t=0 , block A is given a velocity v_(o) in horizontal direction. Let v_(1) and v_(2) be the velocity of A & B at time 't' . Then choose the correct graph between v_(1) or v_(2) and t :
