A basketball has a mass of 1 kg and is traveling 12 m/s.

What would happen to the velocity if the momentum of the basketball were cut in half?

Answers

Answer 1

Answer:

[tex]6\:\mathrm{m/s}[/tex] (The velocity would also be halved)

Step-by-step explanation:

The momentum of an object is given as [tex]p=mv[/tex] where [tex]m[/tex] is the mass of the object and [tex]v[/tex] is the velocity of the object.

Because mass is constant, if the momentum ([tex]p[/tex]) was cut in half, the velocity of the basketball would also be halved:

Let [tex]p_1[/tex] be the initial momentum and [tex]p_2[/tex] be the final momentum:

[tex]\frac{1}{2}p_1=p_2,\\\frac{1}{2}mv_1=mv_2, \\\fbox{$\frac{1}{2}v_1=v_2$}[/tex]

Therefore, the basketball's new velocity is [tex]\frac{1}{2}\cdot 12=\fbox{$6\:\mathrm{m/s}$}[/tex].

Answer 2
a basketball has a mass of 1kg and is traveling 12 m/s
6 m/s

Answers

Answer:

The correct answer is E, 551.6 square feet.

Step-by-step explanation:

I think we can assume that the two ends are perfect semi-circles, although that's not clearly specified.

In that case, the total area we have is that of a 15x25 foot rectangle, plus a circle with a diameter of 15ft.

So lets work that out.  The rectangle is easy, as the area is just width times height. 15 ft * 25 ft is 375 ft²

The area of a circle is defined as πr².  We're given the diameter, which is twice the radius, so the collective area of the two ends would be π × 7.5² which equals π × 56.25, or approximately 176.7 square feet.

Now we just need to add those together:

375 + 176.7 = 551.7

The difference in answer will be due to rounding, so we know that the correct answer is E, despite their answer being rounded incorrectly.

A pair of jeans are originally $39.50 and are 15% off. The sales tax is 7%. After the discount and tax, how much will the total be ?

A) $6.34
B) $7.82
C) $30.81
D) $35.93

Answers

Answer:

d

Step-by-step explanation:

85% of 39.50 is 33.575, 7% of 33.575 is 2.35, add 33.575 and 2.35 and you get 35.925, round it and you get 35.93

The amount paid after deducting discount and adding tax is $35.93

How to solve amount paid after discount

Original price = $39.50Discount off = 15%

New price = 85% of $39.50

= 0.85 × 39.50

= $33.575

Tax = 7% × $33.575

= 0.07 × 33.575

= $2.35025

Total price paid = New price + Tax

= $33.575 + $2.35025

= 35.92525

Approximately,

$35.93
