Describe the conversions between potential and kinetic energy that occur when you shoot a basketball at a basket

Answers

Answer 1

Answer: When you shoot a basketball at a basket, the energy from your hands is transferred into the basketball. When you hold the ball up in preparation to shoot, it has potential energy, meaning that it has stored energy that can turn into kinetic energy. When you shoot it, that potential energy turns into kinetic energy, causing the basketball to move.

An object has a mass of 48g and a volume of 6cm cubed (like a little 3 above the m) Calculate the density of this object

Answers

   Density = (mass) / (volume)

    = (48 g) / (6 cm³)

      = (48 / 6) (g / cm³)

=    8 g/cm³

A dryer runs on 240 V with a resistance of 30.0 Ω. What is the current of the dryer?

Answers

Answer:

Current, I = 8 Amps

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

$V = IR$

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Given the following data;

Resistance, R = 30 ohms

Voltage, V = 240V

To find the current;

$I = \frac {V}{R}$

$I = \frac {240}{30}$

Current, I = 8 Amps

Therefore, the current of the dryer is 8 Amperes.

A ski jumper competing for an Olympic gold medal wants to jump a horizontal distance of 135 meters. Thetakeoff point of the ski jump is at a height of 25 meters. With what horizontal speed must he leave the jump?
a. What do you know?
b. What do you need to solve for?
c. What equation(s) will you use?
d. What is the solution to this problem?

Answers

A. We know that the height (h) = 25 m, and the distance (x) = 135 m.

B. We need to find the time flight first (t), then we can find easily the horizontal velocity ( $v_(x)$ . )

C. Because this is a projectile motions, so horizontal velocity is constant, but the vertical velocity is change because of the gravitational acceleration.
So we can use : $h = (1)/(2) g t^(2)$ ,

Note : Time that will be exist is a time from a land to the takeoff point, that can be called as the time flight.
Then we use, $x = v_(x) t$ , to find the horizontal velocity.

D. We know that :
$h = (1)/(2) g t^(2)$ , so by insert the numbers, and assune that the (g = 10 m/ $s^(2)$ ), we get that ( t = $√(5)$ . )
After that by using $x = v_(x) t$ , we can get that $v_(x) = 27 √(5)$
