PLEASE ANSWER ASAP WILL GIVE BRAINLIEST What would be the mass of a rock falling from the sky if it hits the ground with a force of 147 N? (Hint: think about the acceleration all falling objects have!)

m

=

15

k

g

Explanation:

Force is given by Newton's second law as the product of an object's mass and acceleration,

→

F

=

m

→

a

.

We are given that

→

F

=

147

N

(downward), and we know that the acceleration of an object in free-fall is equal to

−

g

, or

−

9.8

m

s

2

. We can rearrange the equation for force to solve for mass.

⇒

m

=

(

F

a

)

=

Explanation:

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
