Question

What is the magnitude of the impulse of force shown in the following figure
(1) 100 NS
(3) 1000 Ns
(2) 900 Ns
(4) 1100 N​

Answer 1

Answer:here is ur answer

Explanation:

Impulse=area enclosed by force -time curve

So..... area under the curve - time curve= impulse

[100*10]-10

1000-10

900Ns

Therefore answer is 900Ns

Answer 2

The magnitude of the impulse of force is 900 Ns.

Given: A plot between force (F) and time (t)

To Find: The magnitude of the impulse of force

Solution:

• Impulse is a term that is used to describe the effect of a force acting over a particular time to change the momentum of a body. The impulse can be related to force and time by the formula,

                     Impulse (I) = Force (F) × time (t)             .... (1)

• Impulse can also be calculated by finding the area under the curve of a plot of force against time.

In the question given, it is a plot of force against time. Hence, we can find the impulse by calculating the area under the curve;

                      Impulse (I) = 100 × ( 10 - 1 ) Ns

                                        = 100 × 9 Ns

                                        = 900 Ns

Hence, the magnitude of the impulse of force is 900 Ns.
