What is the mass of a baseball that has a kinetic energy of 100 J and is traveling at 5 m/s?

Andrei [34K]

The formula of the kinetic energy is:
K.E = $\frac{1}{2}$ mv²

The given are
K.E = 100 J
v = 5 m/s

Plug them in:

100 = $\frac{1}{2}$ m × (5)²
100 = $\frac{1}{2}$ m × 25
100 = 12.5m
Divide by 12.5 on either sides to isolate m

$\frac{100}{12.5}$ = $\frac{12.5m}{12.5}$
12.5 and 12.5 cancels out
8 kg = m
The mass of the baseball that has a kinetic energy of 100 J and speed of 5 m/s is 8 kg
