Atoy car of mass 0.15kg accelerates from a speed of 10 cm/s to a speed of 15 cm/s. what is the impulse acting on the car? a. 7.5 mn sb. 37.5 mn sc. 0.75 n s d. 3.75 n sif you could explain how you got it i would appreciate that

Answer : The correct option is, (A) 7.5 mN.s

Explanation :

Impulse : It is defined as the force applied to an object for a certain amount of time.

Formula used :

As we know that:

Thus, formula of impulse will be:

where,

I = impulse  = ?

m = mass = 0.15 kg

= change in speed of velocity =     (1 m = 100 cm)

Now put all the given values in the above formula, we get:

     (1 N.s = 1000 mN.s)

Therefore, the impulse acting on the car is, 7.5 mN.s

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
