Thanks for the question,
Asteroids: These are rocky and airless plates from the formation of planets in our solar system. It basically revolves around our sun in the space barrier between Mars and Jupiter and moves in the size of cars to smaller planets.
Comets: comets are the most polluted glaciers of ice and dust created at the time of the birth of the solar system 4.6 billion years ago. Many comets have a fixed orbit around the outer surface of the solar system beyond the planet Neptune.
Meteoroids, Meteorites, Meteorites: Meteoroids are small asteroids or broken comet fragments and sometimes planets. They vary in size from sand dune to three large stones in diameter. When meteoroids collide with the earth's atmosphere, they form meteors. When those meteors survive space and reach the surface of the planet, their remains are called meteorites.

Explanation:
It is given that,
Initial speed of the automobile, u = 65 km/hr =
Final speed of the automobile, v = 0
Deceleration of the automobile,
We need to find the distance covered by the car as it comes to rest. It can be calculated using third equation of motion as :
So, the acceleration of the car is . Hence, this is the required solution.
Answer:
a. tension of the cable attached to chair = 2.77kN
b. speed of the chair = 10.38m/s
Explanation:
A. tension of the cable is calculated by mass of the chair multiply by gravitational acceleration.
Tension(T) = m*g
where, m= 283kg
length of cable = 11m
and g=9.8m/s2
tension = mg = 283*9.8
=2773.4 N = 2.77kN
b. speed of the chair =
= 10.38m/s
