Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Diego kicks a soccer ball from the end line. His fellow students time and mark the soccer ball as it moves down the field. The graph represents the ball's progress.

Based on the graph, during what time is the soccer ball not moving?

A) from 0 to 1.5 seconds

B) from 3.0 to 4.5 seconds

C) from 4.5 to 5.0 seconds

D) from 1.5 to 3.0 seconds

Answer 1

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

Further explanation

Acceleration is rate of change of velocity.

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

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

a = acceleration ( m/s² )

v = final velocity ( m/s )

u = initial velocity ( m/s )

t = time taken ( s )

d = distance ( m )

Let us now tackle the problem!

$\texttt{ }$

This problem is about Average Speed

We will use this following formula:

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

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.
