Question

The kinetic energy of an object moving at a speed of 14.2m/s was determined to be 950.0 ). What is the mass of the object? 4.848Kg 66.9Kg 585Kg 9.42 Kg Multiple Choice 1 point

Answer 1

Here's how to solve this problem:**1. Recall the formula for kinetic energy:**Kinetic Energy (KE) = (1/2) * mass (m) * velocity² (v²)**2. Rearrange the formula to solve for mass:**m = 2 * KE / v²**3. Plug in the given values:*** KE = 950.0 J* v = 14.2 m/sm = 2 * 950.0 J / (14.2 m/s)²**4. Calculate the mass:**m = 1900 J / 201.64 m²/s²m ≈ 9.42 kg**Therefore, the correct answer is 9.42 Kg.**
