Final answer:
To find the mass of Frankenstein's monster, given its kinetic energy and velocity, we use the kinetic energy formula KE = 0.5mv². After rearranging and plugging in the values, we calculate that the mass of the monster is 181.25 kg.
Step-by-step explanation:
The question asks for the mass of Frankenstein's monster based on the energy generated and its velocity. Using the formula for kinetic energy (KE) which is KE = ½mv², where m is mass, and v is velocity, we can rearrange the formula to solve for mass (m).
Given that the kinetic energy (KE) is 1450J and the velocity (v) is 4.0 m/s, we get:
1450 J = ½m(4.0 m/s)²
m = (2 × 1450 J) / (4.0 m/s)²
m = 2900 J / 16 m²/s²
m = 181.25 kg
Therefore, the mass of Frankenstein's monster is 181.25 kg.
