A ping 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?
1 answer:
Answer:
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.
