A body is projected with angle 60 with horizontal with velocity 147 m/s time taken to reduced to 45
1 Answer
Malhar Pandya
As we know that the horizontal component of velocity will remain constant ( and,in this question, is equal to 73.5).since the horizontal velocity itself is greater than 45 ,it is not possible for the velocity of the body to attain this value,and the least value of velocity attainable by the body will be 73.5 at the highest point of its motion

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.
