a pump ejects 12000 kg of water at speed of 4 m/s in 40 seconds. find the average rate at which the punp is
1 Answer
Raja Karthik
mass (m) = 12000kg
velocity (v) = 4m/s
time (t) = 40s
Force = (m x v) / t
= (12000 x 4) / 40 = 1200 N

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.
