Explanation:
it could be possible if the car has all the right aro dynamics
Answer: C
Explanation: Convert 50 km to m, and you get 50,000. You then divide by 14 and get 3,571.42....The closest answer is C
A cyclist can increase the speed of their bike in various ways such as, changing gears, positioning themselves properly, increase the pedalling rate
<h3>
Ways in which a cyclist can increase the speed of a bicycle</h3>
Bicycle riders could accelerate/ increase their speed in various ways
- By Changing the gears and by doing so increasing the speed
- By Positioning themselves in a streamlined manner, this is so that they become aerodynamic hence they cut across airflow.
- By increase the rate at which they are pedalling the bicycle.

The average force on the car=3857 N
Explanation:
mass of car= 1000 kg
initial velocity= Vi=0
Final velocity= Vf=27 m/s
time= t= 7 s
using the kinematic equation,
Vf= Vi + at
27=0+a (7)
a=3.857 m/s²
Now the force is given by F= m a
F=1000 (3.857)
F=3857 N
It would increase--materials expand as they get hotter.
