Abaseball with a mass of 300 g has a kinetic energy of 304 j. calculate the speed of the baseball

The formula for kinetic energy is equal to 1/2mv^2, where "m" is the mass of the object (in kilograms) and "v" is equal to the velocity of the object (in meters per second). To calculate the speed, simply plug in the values and solve.

KE = 0.5mv^2

304 J = 0.5(0.3 kg)v^2         -mass converted from grams to kilograms

v = 45.02 m/s

The baseball is travelling about 45.02 meters per second.

Hope this helps!

the answer is a)
