The acceleration is
Explanation:
We can answer this question by using Newton's second law, which states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:
where
F is the force
m is the mass
a is the acceleration
In this problem, we have
m = 25 kg is the mass of the rider+bicycle
F = 400 N is the force
Solving for a, we find the acceleration:

A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.
The expression of an electronic component, circuit, or system's resistance to alternating and/or direct electric current is called impedance, indicated by the letter Z. Resistance and reactance are two distinct scalar (one-dimensional) phenomena that combine to form impedance, a vector (two-dimensional) variable.
=
(for a pure resistor where Z=R,preserving the form of the DC Ohm's law).
I = 20 A
Therefore, A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.
