A 0.150-kg baseball traveling 32.0 m/s strikes the catchers mitt, which, in bringing the ball to rest, recoils backward 15.0 cm.
What was the magnitude of the average force applied by the ball on the
I solved a question that uses this formula, (E= RH(1/nf2 -1/ni2)
My Answer came out (-)1.2 x 10^-18 and my other answer is (-)2.3 x 10^-18
So which Emits the Most energy?
Is it the negative (-1.2E-
