Answer:
28 J
Explanation:
Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both.
In physics, mechanical energy (Emech) is the energy associated with the motion and position of an object usually in some force field.
Therefore:
ME = KE + PE = 25 + 3 = 28 J
The turtle's shell would be able to heal and it has two parts, the upper called the carapace and the lower called the plastron.
3 x 108 is roughly 300 people.
Half of them have cars. Half of 300 = 150.
150 x 12000 = 1,800,000 miles driven.
Each car gets 20mpg.
Solve for the # of gallons consumed.
Answer:
one at the edge
Explanation:
The relation between the linear velocity and the angular velocity is given by
v = r x ω
Where, v be the linear velocity, ω be the angular velocity and r be the radius of the circular path.
As the angular velocity is constant, thus, the linear velocity depends on the radius of circular path.
So, the horse which is near to the edge has maximum radius of circular path in which it is rotating. So, the horse which is at the edge of the merry go round has maximum linear speed.
