You lift the child by using your elbow joint (pivot point). If the child's mass is 27 kg and distance from child to elbow joint is 0.40 m, calculate the torque? C.A ball slides with initial velocity 0.9 m/s on a frictionless surface and collides with another identical ball of mass at rest. The balls stick together after the collision. Calculate the final velocity of the balls?
