Question

C.) What is the kinetic energy of a 400 g baseball traveling at 80

miles per hour? 1 mile= 5280 ft, 1 ft = 12 inches, 1 inch = 2.54 cm pls help

Answer 1

KE = 1,280,000g/m/h

Step-by-step explanation:

use the formula, KE = 1/2m(v^2)

KE = 1/2 (400) (80^2)

KE = (200) (6400)

KE = 1,280,000g/m/h
