A particle is thrown with a velocity of u m/s. It passes A and B at time t1 = 1s and t2 = 3s. The value of u is (g=10 m/s2).

Final time = 4 sec 4= 2u sino/h4 = 2u Sin30/10 U= 40(Total time = 3+1=4)(Angle of elevation = y/x)

At max. height, t=2s (as this position is midway between t=1s and t=3s)

t=usin@/g( to reach the max. height)

t= usin30°/g

2= u*1/2*10

U=2*2*10

U=40ms–¹.

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
