The diagram shows a tennis ball being thrown vertically into the air. When the ball just left the players hand it is at the speed of 5.0 m/s . The tenis ball has the mass of 0.058 kg. Write down the equation that links kinetic energy to mass and speed

1. KE = ½mv²

2. The kinetic energy of the tennis ball is 0.725 J

Explanation:

The following data were obtained from the question:

Mass (m) = 0.058 kg

Velocity (v) = 5.0 m/s

Kinetic energy (KE) =.?

1. Defining an expression which relates kinetic energy, mass and speed of an object.

Kinetic energy is simply defined as the energy possess by an object in motion. Mathematically, kinetic energy can be represented as:

KE = ½mv²

Where

KE => is the kinetic energy.

m => is the mass of the object.

v => is the velocity of the object.

2. Determination of the kinetic energy of the tennis ball.

Mass (m) = 0.058 kg

Velocity (v) = 5.0 m/s

Kinetic energy (KE) =.?

KE = ½mv²

KE = ½ × 0.058 × 5²

KE = 0.029 × 25

KE = 0.725 J

Thus, the kinetic energy of the tennis ball is 0.725 J.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
