An object moving with a speed of 48 m/s has a kinetic energy of 4,632 J, what is the mass, in kg, of the object?
Please note the following:
Use g= 9.8 m/s2 for gravity
• Do not use commas in your answer to show place value.
• Do not use units in your answer.
As you work, please round to the nearest hundredth.
• Round your final answer to the nearest tenth if necessary. Plz help it’s a quiz

4.0 Kg

Explanation:

From the question given above, the following data were obtained:

Velocity (v) = 48 m/s

Kinetic energy (KE) = 4632 J

Mass (m) =?

Kinetic energy can be defined as the energy possess by a moving object. Mathematically, it is expressed as:

KE = ½mv²

Where

KE => kinetic energy

m => mass of object

v => velocity

With the above formula, we can obtain the mass of the object as follow:

Velocity (v) = 48 m/s

Kinetic energy (KE) = 4632 J

Mass (m) =?

KE = ½mv²

4632 = ½ × m × 48²

4632 = ½ × m × 2304

4632 = m × 1152

Divide both side by 1152

m = 4632 / 1152

m = 4.0 Kg

Therefore, the mass of the object is 4.0 Kg

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
