The answer would be 15,120
Area of a triangle = 1/2 base * height
A = 1/2 (10)* 20
A= 5*20
A = 100 cm^2
Choice C
Answer: Vertically
The line crosses vertically for a y intercept
The maximum height reached is 2.87 meters
<h3>What is maximum height?</h3>
The maximum height of an object is the highest vertical position along the trajectory of the object.
The given parameters are:
--- the initial velocity
--- the final velocity
--- the acceleration
To calculate the height (s) of the ball, we make use of the following equation of motion:

Substitute known values


Collect like terms

Substitute 9.8 for g


Divide both sides by 19.6

Hence, the maximum height reached is 2.87 meters
