Answer:
3. is made of nucleotides
The first thing we need to do is figure out what equation to use. We will use the following kinematic equation...
Δx = (final velocity + initial velocity) x time / 2
We know that the car accelerates from rest, so initial velocity = 0 m/s
We also know final velocity = 20 m/s and time = 12s
Now we just need to plug everything in.
Δx = (20 x 12)/2 = 120 meters
Answer:
The answer is
<h2>2560 J</h2>
Explanation:
The kinetic energy of an object given it's mass and velocity can be found by using the formula

where
m is the mass
v is the velocity
From the question
m = 80 kg
v = 8 m/s
The kinetic energy is

We have the final answer as
<h3>2560 J</h3>
Hope this helps you
