An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object? Formula=1/2mv^2 a(7.5 b(15 kg c

Westkost [7]

Hello!

An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object?

We have the following data:

KE (Kinetic Energy) = 480 J

m (mass) = ? (in Kg)

v (speed) = 8 m/s

Formula to calculate kinetic energy:

$KE = \dfrac{1}{2} *m*v^2$

Solving:

$KE = \dfrac{1}{2} *m*v^2$

$480 = \dfrac{1}{2} *m*8^2$

$480 = \dfrac{1}{2} *m*64$

$480*2 = 64*m$

$960 = 64m$

$64m = 960$

$m = \dfrac{960}{64}$

$\boxed{\boxed{m = 15\:Kg}}\end{array}}\qquad\checkmark$

Answer:

15 kg
