Question

Transcribed Image Text:**76. Round and Round**
Little Jay is enjoying his first ride on a merry-go-round. (He is riding a stationary horse rather than one that goes up and down.) A schematic view of the merry-go-round as seen from above is shown in Fig. 11-47a with a convenient coordinate system. A bit after the merry-go-round has started and is going around uniformly, we start our clock. Little Jay’s position and velocity at time \( t_1 = 0 \) are shown as a dot and arrow. At \( t_1 = 0 \) is the net force acting on Jay equal to zero? If it is, write “Yes” and give a reason why you think so. If it isn’t, write “No” and specify the type of force and the object responsible for exerting it.
**Figure 11-47a**
Problem 76.
- A circle is shown with a coordinate system (\( x \) and \( y \) axes). The velocity vector \( \Delta \mathbf{v} \) is shown at \( t_1 = 0 \).
For the next six parts, specify which of the graphs shown in Fig. 11-47b could represent the indicated variable for Jay’s motion. If none of the graphs work, write “N.”
**Figure 11-47b**
The graphs depict various possible motion-related variables over time, labeled A to F.
- **Graph A**: Represents a linear increase over time.
- **Graph B**: Represents a sinusoidal wave starting at zero.
- **Graph C**: Represents a sinusoidal wave starting at a maximum point.
- **Graph D**: Represents a sinusoidal wave starting at zero but is inversely oriented compared to B.
- **Graph E**: Represents a constant value over time.
- **Graph F**: Represents a sinusoidal wave similar to B but starting from a point before reaching zero.
**Problem 76 Variables:**
(a) The \( x \)-component of Jay’s velocity
(b) The angle Jay’s position vector makes with the \( x \) axis
(c) The \( y \)-component of the force keeping Jay moving in a circle
(d) Jay’s rotational velocity
(e) Jay’s translational speed
(f) The \( x \)-component of Jay’s position
