KE = 8887.5 J
<h3>Further explanation</h3>
Given
speed = 15 m/s
weight = 79 kg
Required
KE-Kinetic energy
Solution
Energy is the ability to do work
Energy because its motion is expressed as Kinetic energy (KE) which can be formulated as:
Input the value :
KE = 1/2 x 79 kg x 15² m/s²
KE = 8887.5 J

Answer:
a) W = - 1.752 10⁻¹⁸ J, b) U = + 1.752 10⁻¹⁸ J
Explanation:
a) work is defined by
W = F . x
the bold letters indicate vectors, in this case the force is electric
F = q E
we substitute
F = q E x
the charge of the electron is
q = - e
F = - e E x
let's calculate
W = - 1.6 10⁻¹⁹ 365 3 10⁻²
W = - 1.752 10⁻¹⁸ J
b) the change in potential energy is
U = q ΔV
the potential difference is
ΔV = - E. Δs
we substitute
U = - q E Δs
the charge of the electron is
q = - e
U = e E Δs
we calculate
U = 1.6 10⁻¹⁹ 365 3 10⁻²
U = + 1.752 10⁻¹⁸ J
