Aping pong ball has a mass of about 2.45 grams. suppose that forrest gump hits the ball across the table with a speed of about 4.00 m/s. what is the ball’s ke?

0.0196 Joules

Explanation:

Kinetic energy is half the product of mass and velocity squared.

K.E=0.5 m*v^2; The m is the mass in kilograms and v is the velocity in meters per second.

We will convert grams to kilograms:

2.45 grams = 0.00245 kilograms.

Calculating kinetic energy:

mass:0.00245 kg

velocity:4 m/s

K.E = 0.5 *0.00245*4^2 = 0.0196 Joules.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
