Question

reflection questions:

1. a surfer with a mass of 50 kg is being pushed forward by a wave with a force of 75 n. what is her acceleration?

acceleration = force ÷ mass
= type answer n ÷ type answer kg
= type answer m/s²

1. you and your friend are having a shopping cart race down the freezer aisle of the market. your cart is full, and your friend’s cart is empty. how might newton’s second law apply to this scenario? who will win, and why?

newton’s second law applies to this scenario because
type answer here
i think type answer here will win because type answer here

Explanation:

Step1: Substitute values into formula

Given \(F = 75\space N\) (force) and \(m=50\space kg\) (mass). Using \(a=\frac{F}{m}\), we substitute the values: \(a = 75\space N\div50\space kg\).

Step2: Calculate acceleration

\(a=\frac{75}{50}= 1.5\space m/s^{2}\).

For the second part:

Newton's second law \(F = ma\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration) applies. Assuming the same pushing force (\(F\)) is applied to both carts. Since \(a=\frac{F}{m}\), the cart with less mass (\(m\)) will have a greater acceleration (\(a\)). The empty cart has less mass than the full - cart.

Answer:

1.
First blank: \(75\)
Second blank: \(50\)
Third blank: \(1.5\)
2.
Newton’s second law applies to this scenario because the motion (acceleration) of the carts is related to the force applied on them and their masses (\(F = ma\)).
I think the friend’s (empty) cart will win because, assuming the same pushing force, according to \(a=\frac{F}{m}\), the empty cart has a smaller mass and thus a larger acceleration.
