If the force acting on a cart is tripled, what happens to the cart's acceleration? Question 8 options: According to Newton's 2nd law the mass is directly proportional to the acceleration and therefore the cart's acceleration will remain constant if the force is tripled. According to Newton's 2nd law force is inversely proportional to acceleration and therefore the cart's acceleration will be reduced by 1/3 if the mass remains constant. According to Newton's 2nd law force is directly proportional to acceleration and therefore the cart's acceleration will triple if the mass remains constant. According to Newton's 2nd law the mass is inversely proportional to the acceleration and therefore the cart's acceleration will be reduced by 1/3 if the force is tripled
