Question

When a horse suddenly starts moving, the

rider fails backward.

a) Name and state the law used to
explain the above situation.

b) State the law of conservation of

linear momentum and prove it on the basis of second law of motion.

c) State true or false.

An iron ball and a wooden ball of the
same radius are released from a height
in vacuum; the iron ball will reach the
ground first.​

Answer 1

Answer:

true

Explanation:

because of the mass of the iron ball

Answer 2

Answer:

a)Law of innertia

a)It states that when an object is left undisturbed it tends to remain in the same position,until and unless there is an applied unbalance force.

Explanation:

Initially ,Man is at rest as he is on the horse

but as the sudden force applied by the horse ,the man will still tend to be in rest .Logically, the horse is moving forward and the man is still at rest which makes him go in backward direction.

This is Newtons second law called Inertia as explained above.

b)Lets see this on web better explained

c)yes ,iron ball reaches fast .Because the resistence towards the air is less in iron ball as it is heavy as compared to the wooden ball
