Answer:
Acceleration of the car will be 
Explanation:
We have given that car starts from rest so initial velocity of the car u = 0 m/sec
And car traveled 400 m in 10 sec
So distance traveled by car s = 400 m
Time taken to compete this distance t = 10 sec
We have to find the acceleration of the car
From second equation of motion we know that 
So 
So acceleration of the car will be

Answer:
The total mechanical energy of the skydiver is, E = 96402.6 J
Explanation:
Given data,
The mass of the skydiver, m = 100 kg
The speed of the skydiver at 80 m height, v = 60 m/s
The initial velocity of the skydiver, u = 0
Using the III equations of motion,
v² = u² + 2gs
s = v²/2g
Substituting the given values,
s = ½ 60²/ 9.8
= 18.37 m
Hence the initial total distance of the skydiver from the ground initially,
h = s + d
= 18.37 + 80
= 98.37 m
Since the total mechanical energy of a system is conserved, the total mechanical energy of the skydiver at height 'h' is equal to the total mechanical energy at height 'd'.
E = P.E + K.E
= mgh + ½ mu²
= 100 x 9.8 x 98.37 ( ∵ u = 0)
= 96402.6 J
Hence, the total mechanical energy of the skydiver is, E = 96402.6 J
Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules.
Titanium, Lead, Potassium, and Silicon are solids at normal temperature.
Mercury and bromine (Br) are the only liquid elements at standard pressure and temperature (Hg).
<h3>What are chemical elements?</h3>
A chemical element is a species of atoms, including the pure substance made entirely of that species, that have a specific number of protons in their nuclei. Chemical elements, in contrast to chemical compounds, cannot be reduced by any chemical process into simpler molecules.

Answer:
A d-t graph's slope is equivalent to the speed and direction while a v-t graph's slope is equal to its acceleration. A constant slope for a d-t graph means that the speed is constant. The area underneath a v-t graph would be its distance.
