I have a acellus too and got this question correct, so I hope this helps y’all out
It will possibly be A) chemical b/c it can make a sound like when the bar hits the ball it makes a sound correct?! and also it created heat especially when it hits the ball. and when the ball MOVES and the bar HITS it creates kinetic energy, but when you hit the ball it doesn’t create a new substance.
F = m*a, mass times acceleration.
F = 15*10 = 150 N
