Answer:
The change in potential energy of the mass as it goes up the incline is 0.343 joules.
Explanation:
We must remember in this case that change in the potential energy is entirely represented by the change in the gravitational potential energy. From Work-Energy Theorem and definition of work we get that:
Where:
- Gravitational potential energy, measured in Joules.
- Mass, measured in kilograms.
- Gravitational acceleration, measured in meters per square second.
- Change in vertical height, measured in meters.
This work is the energy needed to counteract effects of gravity at given vertical displacement.
If we know that , and , the change in the potential energy of the mass as it goes up the incline is:
The change in potential energy of the mass as it goes up the incline is 0.343 joules.
The answer is c so the area can grow
Answer:
force and mass sorry i dont clear
Explanation:
Total energy before the toss:
Total energy at the roof:
Energy must be conserved so :
If v₁ is the initial velocity and v₂ is the final velocity, which is zero at the roof:
Answer:If she walks 132 and 6 you do 132 x 6 = 792
