In an experiment, James studied the relationship between kinetic energy, mass, and velocity. Four masses were rolled across a smooth surface. If the kinetic energy in Joules remains constant, and the masses change, predict the velocity of the ball with a mass of 40kg

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
