Answer:
a. 0.0 J
Explanation:
Such an object will gain no gravitational potential energy since it moves horizontally.
Gravitational potential energy is the energy possessed by two massive bodies at a distance from one another in the presence of gravity.
- In the horizontal direction, there is no sense of gravity as the body is not moving away or towards the center of the earth.
- Gravitational potential energy is expressed as;
E = mgh
m is the mass
g is the gravity
h is the height
Gravity component in the horizontal direction is 0
Answer:
the number of protons in the atom.
Explanation:
Answer:
The answer is thermal energy
Explanation:
Answer:
v = 2.41 m/s
Explanation:
Here net force on the Skater + snowball is zero
so here we can use momentum conservation for skater + snowball
now we have
so the final speed of skater will be 2.41 m/s
