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

)

=
