Based on the graph, the soccer ball is not moving from C) from 4.5 to 5.0 seconds

$\texttt{ }$

<h3>Further explanation</h3>

Acceleration is rate of change of velocity.

$\large {\boxed {a = \frac{v - u}{t} } }$

$\large {\boxed {d = \frac{v + u}{2}~t } }$

<em>a = acceleration ( m/s² )</em>

<em>v = final velocity ( m/s )</em>

<em>u = initial velocity ( m/s )</em>

<em>t = time taken ( s )</em>

<em>d = distance ( m )</em>

Let us now tackle the problem!

$\texttt{ }$

This problem is about Average Speed

<em>We will use this following formula:</em>

$\texttt{Average Speed} = \texttt{Distance} \div \texttt{Time Taken}$

From 4.5 to 5.0 seconds , there is no change in distance of the ball.

t₁ = 4.5 → s₁ = 65 m

t₂ = 5.0 → s₂ = 65 m

$\texttt{Average Speed} = (65 - 65) \div (5.0 - 4.5)$

$\texttt{Average Speed} = 0 \div 0.5$

$\texttt{Average Speed} = 0 \texttt{ m/s}$

Since the average speed is zero, the ball doesn't move from 4.5 to 5.0 seconds.

Darya [45]

To answer the two questions, we need to know two important equations involving centripetal movement:

v = ωr (ω represents angular velocity <u>in radians</u>)

a = $\frac{v^{2}}{r}$

Let's apply the first equation to question a:

v = ωr

v = ((1800*2π) / 60) * 0.26

Wait. 2π? 0.26? 60? Let's break down why these numbers are written differently. In order to use the equation v = ωr, it is important that the units of ω is in radians. Since one revolution is equivalent to 2π radians, we can easily do the conversion from revolutions to radians by multiplying it by 2π. As for 0.26, note that the question asks for the units to be m/s. Since we need meters, we simply convert 26 cm, our radius, into meters. The revolutions is also given in revs/min, and we need to convert it into revs/sec so that we can get our final units correct. As a result, we divide the rate by 60 to convert minutes into seconds.

Back to the equation:

v = ((1800*2π)/60) * 0.26

v = (1800*2(3.14)/60) * 0.26

v = (11304/60) * 0.26

v = 188.4 * 0.26

v = 48.984

v = 49 (m/s)

Now that we know the linear velocity, we can find the centripetal acceleration:

a = $\frac{v^{2}}{r}$

a = $\frac{49^{2}}{0.26}$
