In a collision an object experiences impulses , this impulse can be determined by
astraxan [27]

In a collision an object experiences impulses, this impulse can be determined by the product of net force exerted upon it in the specific course of time.

<u>Explanation:</u>

An object experiences impulse due to the force exerted upon it in a particular time period.

i.e.

                 \text {Impulse }=F \times \Delta t

Where,

F - Force acted upon the object

\Delta t - time interval for which the force act

According to the definition of Impulse, it is the integral of force (F) that acts upon any object over a time interval ∆t. It produces an equivalent change in the momentum and that too in the same direction as of the applied force (F).

Therefore, in order to find the impulse on an object, we have to find the force acted on it in a specific time interval.

a boy pulls 23 kg box with a 100 N force at 39 above a horizontal surface if the coefficient of kinetic friciton between the box
tatuchka [14]

Answer:

Total work done is 2606.08 J.

Explanation:

Given :

Mass of box , m = 23 kg .

Force applied , F = 100 N .

Angle from horizon , \theta=39^o.

Coefficient of kinetic friction , \mu=0.16.

Distance travelled by box , d = 34 m .

Now ,

Total work done = work done by boy + work done by friction.

W=Fdcos\theta+f_sdcos\theta=Fd-\mu(mg) \\\\W=100\times cos39^o\times 34-0.16\times 23 \times 9.8 \\\\W=77.71\times 34-36.06=2606.08\ J.

Hence , this is the required solution.

If an object is pushed with 10 newtons to the right but friction slows down the object with 5 newtons to the left and a person p
Natasha_Volkova [10]
Yes they are balanced because if it has 10 Newtons to the right and then someone pushes 5 Newtons to the left and then another 5 then that means there is 10 Newtons left and 10 Newtons right
