Question

What is the kinetic energy of a baseball traveling at a 25 mi./s with a mass of 0.56KG

Answer 1

453.25 MJ

Step-by-step explanation:

The formula to find kinetic energy is :

`E_(k) = (1)/(2) X m X v^(2)`

E.k = ?

m = 0.56kg

v = 25mi./s which needs to be converted into metres per second

1mi./s= 1609.34m/s

25 mi./s = 40233.6 m/s.

E.k. = 0.5 × 0.56 × 40233.6²

e.k = 453247919.3J

E.k.= 453.25 MJ
