Question

A ball of mass 5 kg. is acted on force 500 N for 10 sec. then changed in movementam of ball is .. a) 1000N b) 5000 N c) 2000N d) 25,000N ​

Answer 1

Answer:

kvmgl be there at the question in regards mark on

Answer 2

Answer:

The changed momentum of the ball will be b) 5000N.

Explanation:

The rate of change in the momentum is equal to the net unbalanced or external force applied. The force in terms of change in momentum is given by the below-written formula;

$F =\frac{P}{t}$

Where P = change in momentum t = time and F = force

In the question above we have mass = 5 Kg, F = 500 N, t = 10 sec, P = ?

Therefore we have,

$F=\frac{P}{t}$

$500 N =\frac{P}{10 sec}$

$P = 500N$×10sec

$P = 5000 N sec$

Hence the answer for this question is option b) 5000 N.
