calculate the velocity of a 0.1m ball travelling on an section beginning at 180 degrees for 0.5m then transitioning to 330 degrees for 1m then again to 180degrees for 0.5m. the ball has a density of 2.4 kg with time of travel at 3 seconds.
then calculate the change in velocity that would be observed due to kinematics and force principles, then again using newtons second law to calculate the force acting on the object.
