In which experiment, if any, does the graph indicate the presence of a net external force exerted on the two-cart system? D. The riders' seatbelts are too tight giving them a feeling of "heaviness". A student conducts an experiment to verify whether momentum is conserved for a situation in which a collision occurs. Not ready to take a quiz yet? No, because the net centripetal force exerted on the ball is the combination of the tension force from the string and the force due to gravity from Earth. A force is applied to a 2kg object, and measurements of the force as a function of time are shown. Cart X travels in the positive direction along a horizontal surface, and cart Y travels in the positive direction. The tricky part of the math is that you need to recognize the 2.0 m is the diameter and not the radius of the circle. Using the known mass and known velocity for each cart to determine the kinetic energy of the system before and after the collision, because the kinetic energy changes in an inelastic collision.
