Question

How would you calculate the kinetic energy of a 0.148kg (5.22oz) baseball traveling at 40 m/s (90mph)?

Answer 1

Option B. (0.148 × 40²) /2

Step-by-step explanation:

The following data were obtained from the question:

Mass (m) = 0.148kg

Velocity (v) = 40m/s

Kinetic energy (K.E) =?

The kinetic energy of the base ball can be obtained by using ½mv² as follow:

K.E = ½mv²

K.E = ½ × 0.148 × 40²

K.E = (0.148 × 40²) /2
