The correct answer of this question is : D) The initial momentum is 5 kg m/s, and the final momentum is 10 kg m/s

EXPLANATION :

Before going to answer this question, first we have to understand the momentum.

The momentum of a body is the amount of motion contained in a body. Quantitatively momentum is the product of mass with velocity.

Mathematically momentum p = mv.

Here, m is the mass of the body, and v is the velocity of the body.

As per the question, the mass of the ball m = 5 Kg.

The initial velocity of the ball u = 1 m/s.

Hence, initial momentum = m × u

                                          = 5 Kg × 1 m/s

                                          = 5 Kg.m/s

The final velocity of the ball v = 2 m/s

Hence, final momentum p = m × v

                                            = 5 Kg × 2 m/s

                                            = 10 Kg.m/s                        [ans]

<span>The initial momentum is 5 kg m/s and the final momentum is 10 kg m/s

'cause P = m*v, when we increase either m or v, P also increases by the same expression, 

P = 5 * 2 = 10

So, option D is your answer!!

Hope this helps!

Answer:

In general solids are easier to transport than liquids, but the above metal example is a valid one and the only other one that comes to mind is that of concrete. It is mixed as a liquid and transported as such, but then sprayed or laid down to dry and form a solid surface or filler.

ziro4ka [17]

Answer:

1 ) Distribution of mass within the ball

2 ) Height of the ramp

Explanation:

Acceleration of a rolling body down an inclined plane is given by the following formula

a = g sinθ / ( 1 + k² / R² )

k is radius of gyration , R is radius of the spherical object ,

when acceleration is more , velocity will also be more .

for objects in which masses are lying in the periphery like in hollow sphere , the value of k²/R² will be high so denominator of the expression will be high so acceleration will be less , hence velocity on reaching the bottom will be less.

On mass of the ball , velocity will not depend .

If height is increased , ball will have acceleration for greater time so velocity will be high.

On radius it will not depend because , radius r and k increases proportionately.
