Physics! Someone help me! Its due today please!
icang [17]

Step-by-step explanation:

We have,

Mass of ball is 9 kg

Initial speed, u = 5 m/s

Final speed, v = -2 m/s (negative as it bounces off)

(a) The change in velocity of the bowling ball is :

\Delta v=v-u\\\\\Delta v=-2-5\\\\\Delta v=-7\ m/s

(b) Change of momentum of the ball is :

p=m\Delta v\\\\p=90\times (-7)\\\\p=-630\ kg-m/s

|p| = 630 kg-m/s

(c) Impulse momentum theorem states that the change in momentum of the ball is equal to the impulse exerted on the ball. So, impulse is 630 kg-m/s.

(d) Impulse is also given by :

J=F\times t\\\\F=\dfrac{J}{t}\\\\F=\dfrac{630}{0.3}\\\\F=2100\ N

Do question 40 please i need help show your work please i need help so bad
zimovet [89]
So 15% is out of 100%, and the cab company has sent 30 cabs out of x?(x is the total number of cabs). \frac{15}{100} =  \frac{30}{x}

So, by setting up that data we already know, we can make this equation to figure out how many cabs total the company actually has:

<span>15x = 100 * 30
</span>
We do the multiplication on the right side

15x = 3000

And divide to isolate the "X" variable

x = 200

So, the cab company has 200 cabs total, and they sent out 30 of them.
