Question

Two people push a car for 3sec with a combined net force of 200N calucate the impluse provided to the car
​

Answer 1

Answer:

600N s

Explanation:

Time of action t=3 s

Force applied F=200 N

Impulse I=F×t=200×3=600 N s

Answer 2

❥ Two people push a car for 3sec with a combined net force of 200N calucate the impluse provided to the car

$\huge\underline{\overline{\mid{\bold{\pink{ANSWER-}}\mid}}}$

❥ Impulse on the car is 600Ns .

$\Large{\underline{\underline{\bf{GiVen:-}}}}$

❥Force ↠ 200N

❥ Time ↠ 3s

$\Large{\underline{\underline{\bf{Find:-}}}}$

❥ Calucate the impluse provided to the car.

$\Large{\underline{\underline{\bf{SoLuTion:-}}}}$

As we know ,

Impulse ↠ time × force

It is represented by j

So , Now

j = Ft or m(v-u)

It's unit is N-s.

As per the given

j = F * T = 200 N * 3s = 600Ns.

$\therefore\underline{\boxed{\textsf{J is = {\textbf{600Ns}}}}} \qquad\qquad \bigg\lgroup\bold{Impulse \ on \ car} \bigg\rgroup$

Additional Information :-

✦ What is implusion ?

In classical mechanics, impulse (symbolized by or Imp) is the integral of a force, , over the time interval, , for which it acts.

Impulse is the product of force and time, also we can say it as product of mass and change in velocity .

It is represented by j .

Note :-

Since force is a vector quantity, impulse is also a vector quantity.

✦ How do you find impulse ?

The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.

✦ What is the difference between impulse and momentum?

Momentum is mass in motion, and any moving object can

have momentum. An object's change in momentum is equal to its impulse. Impulse is a quantity of force times the time interval. Impulse is not equal to momentum itself; rather, it's the increase or decrease of an object's momentum

✦ Example of impulse ?

• When you hit a ball with a cricket bat, you apply a force for a time(a very short period in this case) to cause a change (or transfer) of momentum in the ball.

• A player in cricket, generally A fielder lowers his hand while catching the ball so that time is increased and less impulse or force acts on his hands.
