A ball is thrown directly upward from the ground with an initial velocity of 4.8 ft./sec. Represent the height of the ball from the ground t seconds after it was thrown upward using the model h(t)
The model h(t) can be represented using the equation:
h(t) = -16t^2 + 4.8t
Where t is the time in seconds and h(t) is the height of the ball from the ground in feet.
To represent the height of the ball from the ground t seconds after it was thrown upward, we can use the equation h(t) = -16t^2 + v0t + h0, where h(t) is the height of the ball at time t, v0 is the initial velocity, and h0 is the initial height (in this case, h0 = 0 as the ball is thrown from the ground).
Given that the initial velocity is 4.8 ft./sec, we can rewrite the equation as h(t) = -16t^2 + 4.8t.
