The velocity of the baseball is 20m/s
Velocity can be described as the speed of an object that is moving in a particular direction
The formula for calculating velocity is
velocity= displacement/time
The first step is to write out the parameters given in the question.
time= 5 seconds
displacement= 100m
The velocity can be calculated as follows;
velocity/displacement
= 100/5
= 20
Hence the velocity of the ball is 20m/s

Step-by-step explanation:
Using the distance formula, we see that the distance between (-4,4) and (-7,3) is
.
Answer:
The maximum height of the arrow is 125 feet.
Step-by-step explanation:
The pathway of the arrow can be represented by the equation,
.....(1)
Where h is height in in feet and t is time in seconds.
It is required to find the maximum height of the arrow. For maximum height,
.
So,

Put t = 2.5 s in equation (1). So,

So, the maximum height of the arrow is 125 feet.
