Answer 1

Regarding the first question:

To find the mass of the object, we can use the formula for kinetic energy:

Kinetic energy (KE) = (1/2) * mass * velocity^2

Given that the kinetic energy is 370 J and the velocity is 10 m/s, we can rearrange the formula to solve for mass:

mass = (2 * KE) / velocity^2

Substituting the given values:

mass = (2 * 370 J) / (10 m/s)^2

= 74 kg

Therefore, the mass of the object is 74 kg.

Regarding the second question:

I apologize, but it seems that the question is incomplete. There is no clear context or information provided to answer the question about the 30.0 kg boy running up a ramp in 3.85 s and using "W of power." Could you please provide more details or clarify the question? I'll be happy to assist you once I have more information.
