What is the mass of a Frisbee that is traveling at 20 m/s and has a kinetic energy of 150 J? Show your work and use significant figures.

Mass, M = 0.75kg

Explanation:

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

Where, K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Given the following data;

Kinetic energy = 150J

Velocity = 20m/s

Making mass the subject formula;

Substituting into the equation, we have;

Mass, M = 0.75kg

50 inches should be the resultant vector
