In the Figure, Point P Is on the Rim of a Wheel

question 73

Short Answer

In the figure, point P is on the rim of a wheel of radius 2.0 m. At time t = 0, the wheel is at rest, and P is on the x-axis. The wheel undergoes a uniform counterclockwise angular acceleration of 0.010 rad/s² about the center O.
(a) At time t = 0, what is the tangential acceleration of P?
(b) What is the linear speed of P when it reaches the y-axis?
(c) What is the magnitude of the net linear acceleration of P when it reaches the y-axis?
(d) How long after starting does it take for P to return to its original position on the x-axis?

Definitions:

Downsloping Curve

Typically refers to a demand curve in economics, indicating that as the price of a product decreases, the quantity demanded increases, and vice versa.

Price Lowering

Price lowering involves reducing the selling price of goods or services, often as a strategy to increase demand or competitiveness in the market.

Monopolist Demand

Monopolist demand refers to the total market demand faced by a monopolist, which is the sole provider of a good or service in the market, and thus faces the downward-sloping market demand curve directly.

Nondiscriminating Monopolist

A monopolist who charges the same price to all customers for a good or service, without price differentiation.
