A ball is thrown into the air from an apartment balcony and falls to the ground. The height of the ball, h metres, t seconds aft er being thrown is given by the formula: h=−5t2+10t+35 How long does it take for the ball to hit the ground
1 answer:
Answer:
seconds
Step-by-step explanation:
When the ball hits the ground, its height will obviously be 0. Therefore, you can set up the equation the following way:
Plugging this into the quadratic equation, you get:
Since the time must be positive, it takes the ball seconds to hit the ground, or around 3.828. Hope this helps!
