Answer:
1) Chemical to mechanical (calories -> muscle contractions)
2) mechanical to mechanical (muscle -> motion)
3) mechanical to thermal (motion -> heat from the body causes sweating)
The potential energy is stored in the body chemically (via food). That potential energy is then released when the body is put in motion.
Explanation:
The y-component of the force on the particle at the given position is 120 N.
<h3>
Electric force on the particle</h3>
The electric force on the particle is determined by applying Coulomb's law and work-energy theorem as shown below;
Fd = W
Where;
- F is the applied force
- d is the distance
- W is potential
F = W/d
F = 60/0.5
F = 120 N
Thus, the y-component of the force on the particle at the given position is 120 N.

Answer:
6 second
Explanation:
initial velocity of ball, u = 60 m/s
g = 10 m/s^2
Let the ball takes time t to reach at the maximum height
We know that at maximum height, the velocity of ball is zero.
v = 0 m/s
Use first equation of motion
v = u + gt
0 = 60 - 10 x t
t = 6 second
Thus, the ball takes 6 second to reach to maximum height.
