Front

What is the maximum height of a projectile?

Back

The maximum height is the highest point reached by the projectile, calculated using the vertex of the parabolic equation.

Front

What is the formula for the height of an object in projectile motion?

Back

s(t) = -16t^2 + vt + h, where v is the initial velocity and h is the initial height.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x = 0.

Front

How do you determine the x-coordinate from a system of equations?

Back

You can isolate x in one equation and substitute it into the other equation to find its value.
