Multiple Choice

When they solve 7 feet as the stat and 24 ft/sec as the initial velocity, what will be the new quadratic equation if the reaches 10 feet?

• $$-16t^2+24t+7$$  

• $$-16t^2+24t-7$$  

• $$-16t^2+24t+3$$  

• $$-16t^2+24t-3$$  

Multiple Choice

Using the equation they set up from Elton Brand's stat, calculate the value(s) of t when the ball reaches a height of 10 feet. Round your answer to the nearest hundredth.

• 14 sec and 1.36 sec

• 0.14 and 1.4 sec

• 0.14 sec and 1.36 sec

​Solution:

Multiple Choice

Based on the values of t they just calculated, what is the value of t when the ball reaches its maximum height.

• 7.5 sec

• 0.75sec

• 75 sec

​Answer:

Multiple Choice

With the equation  $$-16t^2+24t+7$$   calculate the maximum height when the average time is 0.75 seconds. Round off your answer to the nearest hundredths.

• 1.6 ft

• 160 ft

• 16ft

​Simply substitute the value of t which is 0.75 to the original equation

Now let's play basketball!
