Answer:
The velocity after time t=7s. is 32 feet/s
Step-by-step explanation:
Given equation is v=(-32)t+256.
Where, v is velocity in feet/sec and t is time in seconds.
The figure show that graph of equation.
To find velocity after time t=7s.
Step 1 : Draw a graph of equation with time on x-axis and velocity of y-axis.
Step 2: Draw a line t=7and extent until it intersects with the equation of line.
Step 3: From point of intersection, draw a line parallel to x-axis and let it intersect the y-axis.
Wherever the line intersect with y-axis is answer for velocity after time t=7s.
From the figure,
The velocity after time t=7s. is 32 feet/s
<em>Verification,</em>
v=(-32)t+256.
When t=7s
v=(-32)(7)+256.
v=32feet/s
