A 0.250 kg car rest rolls down a frictionless incline from a starting height of 0.75 m what is the final velocity of the car? SHOW ALL WORK. Also what difference would it make if it is not frictionless? Please and thank you!

v = 3.83 m/s

Explanation:

Given that,

The mass of a car, m = 0.250

It rolls down a frictionless incline from a starting height of 0.75 m

We need to find the final velocity of the car. Let v be the velocity of the car. It can be calculated using the third equation of motion i.e.

Here,

u = 0 and a = g

So, the final velocity of the car is 3.83 m/s.

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
