Two frictionless lab carts start from rest and are pushed along a level surface by a constant force. Students measure the magnitude and duration of the force on each cart, as shown in the partially completed data tableabove, and calculate final kinetic energy and momentum. Which cart has a greater kinetic energy at the end of the push?
