Find the mass and show all the work please and show the answer. Thank you.

75 kg.

Explanation:

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

Kinetic energy (KE) = 937.5 J

Velocity (v) = 5 m/s

Mass (m) =?

Kinetic energy (KE), mass (m) and velocity (v) of an object are related according to the following equation:

KE = ½mv²

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

Kinetic energy (KE) = 937.5 J

Velocity (v) = 5 m/s

Mass (m) =?

KE = ½mv²

937.5 = ½ × m × 5²

937.5 = ½ × m × 25

937.5 = m × 12.5

Divide both side by 12.5

m = 937.5 / 12.5

m = 75 Kg

Therefore, the mass of the object is 75 Kg.
