Question

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

Answer 1

Answer:

The answer is A

Explanation:

I just C in and it was wrong, The answer is A.

Answer 2

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

$\texttt{ }$

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.
