Hi there!

Acceleration = change in velocity / change in time = Δv/Δt

Thus:

a = (75 - 15)/4 = 60/4 = 15 mi/hr²

Equation you need to use is a=Vf-Vi/t
Vi=initial velocity
Vf= Final Velocity
Write out the variables and their numbers
Vf=75 mi/hr Vi=15 mi/hr t=4 seconds
Plug it all in
75-15/4
60/4
a=15 mi/hr^2

What is the difference between a mineral and a rock
Sedbober [7]

A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes.

A rock is an aggregate of one or more minerals. It may also contain organic remains and mineraloids apart from regular mineral formations. Since rocks vary in their mineral and chemical composition, they are classified according to the process of their formation.

In order for an object to accelerate, a forcegravityfrictiona swing must be applied.
vodomira [7]
<span>In order for an object to accelerate, a <u>force</u> must be applied. It follows Newton’s second law of motion where it states that a body at rest remains at rest unless a force is acted upon it. When you move an object, you are exerting a force onto it. By exerting a force on the object, you are actually displacing it from its initial position. You cannot apply force to the object without altering its position. Keep in mind that when you exert work, you are exerting energy too. </span>
