hit the green can be represented by the equation - 16t2 + 706 + 5 = -4. How long does it
take the ball to land on the green?
It takes the ball |
seconds to land on the green.
Answer:
Time, t = 4.5 s
Step-by-step explanation:
The number of seconds t it takes the ball to hit the green can be represented by the equation :
It means that the initial velocity is 70 ft/s. The above equation becomes:
It is required to find the time taken by the ball to land on the ground. It is a quadratic equation. The solution of quadratic equation is given by :
t = −0.125 and t = 4.5 s
Time cannot be negative. So, the time taken by the ball to land on the ground is 4.5 seconds.
