Question

What is the mass of an object that creates 33,750J of energy by traveling at 30m/s?

Answer 1

Apply the famous einteins equation....E=mc^2

Answer 2

Answer:

m = 75 Kg

Explanation:

Given data:

Energy = 33750 J

Speed of object = 30 m/s

Mass of an object = ?

Solution:

Formula:

E = 1/2mv²

by putting values,

33750 J = 1/2 × m × (30 m/s)²

m = 2×33750 J/ (30 m/s)²

m = 67500 J /900 m²/s²

J = kgm²/s²

m = 75 Kg
