    The tangential and normal components of acceleration are the projections of the acceleration vector onto T and Nrespectively. Appreciation of momentum conservation issues in the context of ethical transport design. The torque is greater when the distance, force, or perpendicular components are greater. The negative sign of means the resultant moment is clockwise. We do this using the linear mass density.

    The cross product method for calculating moments says that the moment vector of a force about a point will be equal to the cross product of a vector r from.Given that the plank is in equilibrium, it means the forces should all be equal in the vertical plane, and the moments should be equal both in the clockwise and anticlockwise direction.

    The reason that the maximum velocity keeps decreasing is because when the ball hits the ground it loses energy, so there is less energy that can be converted to kinetic energy, thus the maximum speed will keep decreasing.
