The car's velocity after 5s : 10 m/s
<h3>Further explanation</h3>
Given
velocity=v=72 km/h=20 m/s
time=t = 5 s
acceleration=a = -2 m/s²
Required
velocity after 5s
Solution
Straight motion changes with constant acceleration

vf=final velocity
vi = initial velocity
Input the value :

The car is decelerating (acceleration is negative) so that its speed decreases

Answer:
c) Fullerene and carbon nanotubes because they have empty spaces inside the molecules
Explanation:
Fullerene and carbon nanotubes would be the most desired in order to hold the cancer fighting drugs and to carry them through the body safely.
- These molecules have empty spaces in them.
- The cavities makes it possible for storage.
- As they pass through the body, they can be held perfectly well to their target site of action.
Inertia is the tendency of an object to remain at rest or remain in motion. Inertia is related to an object's mass.
