question 2 and please explaion why that option
![2- The slope of a net force versus acceleration diagram represents which of the following?
(1 Mark) K/U
(a) velocity
(b) mass
(c) weight
(d) time
3 - Answer each question below using Newton's second law. Explain your answers.
(4 Mark) K/U, C
(a) Two cars have the same net force acting on them, but one has more mass than the other.
Which car will have the greater acceleration?
(b) A heavy box of sand is on top of a cart. A person pulls the cart forward with a constant net
force while the sand leaks out of the box and onto the ground. What will happen to the
acceleration of the cart?
4 - A student claims, "If action and reaction forces are equal in magnitude and opposite in
direction, then when you add them together, you will always get zero and nothing will ever
accelerate." Discuss the validity of this statement. (2 Mark) C
5- (a) Using your understanding of gravity and the relationship between force and acceleration,
explain why you might feel heavier when an elevator travels upward and lighter when it travels
downward.
(b) Describe another situation in which someone might encounter a similar combination of
accelerations to those in an elevator.
