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
