Final answer:
The question pertains to Physics, specifically kinematics, and requires additional information to determine all unknowns for a bicyclist speeding up steadily. The average velocity is given as 4.5 m/s, but without time or distance, it's not possible to calculate missing variables like final velocity, total distance, or acceleration.
Step-by-step explanation:
The student's question can be interpreted as a kinematics problem in the subject of Physics. To determine all unknowns for a bicyclist speeding up steadily, we must assume that we are dealing with a constant acceleration scenario and that the average velocity given can be used to find the acceleration and distance traveled over a given time period.
Since the problem provides an average velocity of 4.5 m/s but does not provide the time or the total distance traveled, we are unable to proceed with calculations. Additional information such as the time interval or the distance over which the bicyclist accelerates is needed to solve for the unknowns, like final velocity, total distance traveled, or acceleration.
To solve similar problems, the following kinematic equation can be used when acceleration is constant:
v = u + at
s = ut + ½at2
v2 = u2 + 2as
In these equations, v is the final velocity, u is the initial velocity (zero if starting from rest), a is the acceleration, s is the distance traveled, t is the time, and the symbols represent the usual algebraic operations of addition and multiplication. Utilizing these equations and substituting known values would allow solving for the unknowns.
