ques tion - whether the ball's mas s affec ts the outc ome - quite eas ily .
The ball is a projec tile; the c art is an objec t moving in a s traight line with c ons tant ac c eleration.
You k now the k inematic equations that relate pos ition, time, and veloc ity for this ty pe of motion.
If the ball's mas s is a fac tor in a relevant equation, then it will affec t the outc ome; if not, then it
If y ou perform the ex periment with a heavier ball, the ball's initial veloc ity will be lower, and the
ball will therefore follow a s horter trajec tory and s trik e the trac k c los er to the trigger. But the
k inematic equations tell y ou that the c art will s till be at the s ame loc ation as the ball when the
ball reac hes the trac k . ANSW ER: The ball would s till land in the c art.
The ball would land behind the c art.
The ball would land ahead of the c art. Correct
