Pendulum is released at theta = 90 we want to know speed at theta = 30 so the rate of change of speed ,dv/dt = tangential accelration = tangential force/mass a = mgsintheta /m = m ×10 × ½ /m =5m/s2

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.
