Answer:

20.353125 V

Explanation:

m = Mass of proton =

q = Charge of proton =

= Velocity of proton at point A = 50 km/s

= Velocity of proton at point B = 80 km/s

The relationship derived from energy conservation is as follows:

The determined potential difference is 20.353125 V

The formula used to calculate power is:

Power = Work / Time

Where Work is defined as Force multiplied by Distance, hence:

Power = Force * Distance / Time

This can also be expressed as:

Power = Force * Velocity<span>


Converting the velocity from km/h to m/s:</span>

Velocity = (5 km / h) (1000 m / km) (1 h / 3600 s)<span>
Velocity = 1.39 m/s

The calculated force corresponds to the vertical component of the hiker's weight:

Force = Wy * g = W * sin θ * g

To find the angle θ, we utilize the slope, which is defined as:

slope = tan θ = ratio of vertical to horizontal distance

tan θ = 0.09

θ = 5.14˚

Thus, we have Force = 68 kg * sin(5.14˚) * 9.8 m/s²<span>
Force = 666.4 * sin(5.14) = 59.73 N
