Answer: 53125joules
Explanation: The formula for kinetic energy is 1/2mv^2.
So we would have
1/2[(170)(25x25)]=53125

Explanation:
The magnitude of a point charge is 0.189 x 10⁻⁹C.
<h3>Steps</h3>
We have stated that the point charge's electric field is E=2.5 N/C.
Distance from point charge R = 51 cm = 0.51 m
We are aware that the electric field resulting from a point charge is given as E = 1 / 4π∈₀ × Q / R²
so 2.5 = 9 x 10⁹ Q/ 0.68²
The magnitude of a point charge is 0.189 x 10⁻⁹C.
The electric force per unit charge is referred to as the electric field. It is assumed that the field's direction corresponds to the force it would apply to a positive test charge.
From a positive point charge, the electric field radiates outward, and from a negative point charge, it radiates in.

Answer:
Metabolic power 420.138 W
Explanation:
Given data:
considering drag coefficient Cd = 0.9
Assuming cross section of cyclist A = 0.50 m^2
Take density of air ρ = 1.2 kg/m3
We know that drag force is given as
D = 14.388 N
hence metabolic power is given as
Metabolic power 
= 420.138 W
