Pankaj and Sudhir are playing with two different balls of masses m and 2m

A man standing on the roof of a house of height h throws one particle vertically downwards and another particle horizontally with the same velocity u. Find the ration of their velocities when they reach both the balls stay in our view for the same period. Pankaj and Sudhir are playing with two different balls [...]

Two particles are separated at a horizontal distance x as shown in Fig. 5.57. They are projected at the same time as shown in the figure with different initial speed. Find the time after which the horizontal distance both the balls stay in our view for the same period. Pankaj and Sudhir are playing with [...]

A particle P is projected with velocity u1 at an angle of 30 with the horizontal. Another particle Q is thrown vertically upwards with velocity u2 from a point vertically below the highest point of path of P. both the balls stay in our view for the same period. Pankaj and Sudhir are playing with [...]

Pankaj and Sudhir are playing with two different balls of masses m and 2m, respectively. If Pankaj throws his ball vertically up and Sudhir at an angle theta, both the balls stay in our view for the same period. both the balls stay in our view for the same period. Pankaj and Sudhir are playing [...]
