X=v(initial)t+.5(a)t^2. Car B's displacement can be represented by equation x=45t. Car A can be represented by the equation x=.5(5)t^2. Plug these equations into a graphing calc and find intercept, the x value is time, the y is displacement.
Answer:This is the part of the scientific method that tests your hypothesis. An experiment is a tool that you design to find out if your ideas about your topic are right or wrong.
Explanation:
They are called magnets poles.
Answer:
![\frac{3m + 4.2M}{m+M}](https://tex.z-dn.net/?f=%5Cfrac%7B3m%20%2B%204.2M%7D%7Bm%2BM%7D)
Where m is Ashley's mass and M is Miranda mass, in kg.
Explanation:
Let m be Ashley's mass and M be Miranda mass, in kg.
By the law of momentum conservation, after the hop on, we have the following momentum equation:
mv + MV = (m + M)S
where v = 3m/s is Ashley speed before the hop on, V = 4.2 m/s is Miranda's speed before the hop on. And S is their speed after
![S = \frac{mv + MV}{m+M} = \frac{3m + 4.2M}{m+M}](https://tex.z-dn.net/?f=S%20%3D%20%5Cfrac%7Bmv%20%2B%20MV%7D%7Bm%2BM%7D%20%3D%20%5Cfrac%7B3m%20%2B%204.2M%7D%7Bm%2BM%7D)
