Question

and exerts an es
he horse to move forward and the cart is pulled by the horse.
plain why is it difficult for a fireman to hold a hose, which ejects a large amount
water at a high .
is elected out from the hose in the forward direction comes out with
develoned in the hose in the​

Answer 1

Answer:

*When a fireman holds a hose, which is ejecting large amounts of water at a high velocity, then a reaction force is exerted on him by the ejecting water in the backward direction. This is because of Newton's third law of motion. Hence, it is difficult for him to remain stable while holding the hose.

*

1.According to Newton's third law of motion action and reaction forces are equal.        

2.  force exerted by the cart at rest is equal to the force exerted by the ground.

3. from second law of motion we know that F = ma.

4. here the cart is the motion

5. then there will be an acceleration

 F of moving cart = ma

F of ground = F of cart at rest = ma, but a is 0 because the cart is at rest

F of moving cart not equal to F of cart at rest

Therefore, F of moving cart is more than the F of cart at rest

6. Therefore The cart moves
