I can’t understand I’m sorry but if you need help with math I can help you
Answer:
The impulse on the object is 60Ns.
Explanation:
Impulse is defined as the product of the force applied on an object and the time at which it acts. It is also the change in the momentum of a body.
F = m a
F = m(
)
⇒ Ft = m(
-
)
where: F is the dorce on the object, t is the time at which it acts, m is the mass of the object,
is its initialvelocity and
is the final velocity of the object.
Therefore,
impulse = Ft = m(
-
)
From the question, m = 3kg,
= 0m/s and
= 20m/s.
So that,
Impulse = 3 (20 - 0)
= 3(20)
= 60Ns
The impulse on the object is 60Ns.
Answer:

Explanation:
Average acceleration is found by dividing the change in acceleration by the time.

The shuttle bus has an acceleration of -2.4 meters per square second. It slows from 9.0 meters per second to rest, or 0 meters per second. Therefore:

Substitute the values into the formula.

Solve the numerator.

We want to solve for t, the time. We have to isolate the variable. Let's cross multiply.



t is being multiplied by -2.4. The inverse of multiplication is division, so divide both sides by -2.4



It takes <u>3.75 seconds.</u>
