Answer:
Mass, m = 0.0593 Kg
Step-by-step explanation:
Given the following data;
Velocity = 2.33 m/s
Kinetic energy = 0.161 Joules
To find the mass of the paper airplane;
K.E = ½mv²
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;
K.E = ½mv²
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting the values into the formula, we have;
0.161 = ½*m*2.33²
0.161 * 2 = 5.4289m
0.322 = 5.4289m
Mass, m = 0.322/5.4289
Mass, m = 0.0593 Kg
