Question

Barry Bonds swings a bat which has a mass of 1.5 kg at a velocity of 55 m/s. How many joules of kinetic energy could he give to a ball?

Answer 1

KE = mv2
2
KE = ? J
m = 1.5 kg
v = 55 m/s
KE = 1.5 kg x (55 m/s)2
2
KE = 2,268.75 J

Answer 2

Answer: 2268.75J

Step-by-step explanation:

K.E = (1/2)mv2

m = 1.5 kg

v = 55m/s

K.E = ?

K.E = (1/2)mv2

K.E = (1/2) x 15 x (55)2

K.E = (1/2) x 15 x 3025

K.E = 2268.75J
