Answer:
W = 19.845 J
Explanation:
Work is defined as W = Fdcos, where F is the force exerted and d is the distance. Because the direction the ball is falling is the same direction as the force itself,
= 0 deg, and since cos(0) = 1, this equation is equivalent to W = Fd. In this case, the force exerted is the weight force, which is equivalent to m * g. Substituting you get:
W = mgd = 0.810 kg * 9.8 m/s^2 * 2.5m
W = 19.845 J
Answer:
The kinetic energy is
Explanation:
From the question we are told that
The potential difference is
The potential energy of the end is mathematically represented as
q is the charge on an electron with a constant value of
substituting values
Now from the law of energy conservation
The
Where is the potential energy at the end
So
The negative sign is not includes because kinetic energy can not be negative
