The vertical weight carried by the builder at the rear end is F = 308.1 N
<h3>Calculations and Parameters</h3>
Given that:
The weight is carried up along the plane in rotational equilibrium condition
The torque equilibrium condition can be used to solve
We can note that the torque due to the force of the rear person about the position of the front person = Torque due to the weight of the block about the position of the front person
This would lead to:
F(W*cosθ) = mgsinθ(L/2) + mgcosθ(W/2)
F(1cos20)= 197/2(3.10sin20 + 2 cos 20)
Fcos20= 289.55
F= 308.1N

Meters, Kilometers, and inches. i think i mean you should probably list all the choices if you want an exact answer
During boiling, the temperature of a container of water remains constant because thermal energy of the water is constant during the transformation from liquid to gas.
<h3>What is kinetic energy?</h3>
Kinetic energy is energy possessed by a particle by virtue of its motion. Molecules that compose matter are in constant random motion according to the kinetic theory of molecules.
The temperature of a container of water stops increasing right before it starts to boil and turn into gas because the thermal energy of the water remains constant as it transforms from liquid to gas. The heat that is required to turn the liquid into gas at the boiling point is called the latent heat.

Answer:
a= kinetic energy vs. different masses at same speed, b= kinetic energy vs. same masses at different speeds
Explanation:
graphs are looking at speed so masses don't matter as much. same speed the whole time will equal same kinetic energy the whole time.
