![]() Sand Master also stops your car slowing down when driving in sand traps.ĭouble Dash + Hot Head: this combo is ideal for experienced players and focuses on speed. Big ball makes the ball easier to hit and harder to miss. Sand Master + Big ball: this combo is perfect for beginners. It’s worth progressing through the campaign as earning stars unlocks additional Power Cores. Straight and Steady removes spin on the ball, while the magnet allows you to slingshot your ball down the fairway. Going to be positive 400.Magnet + Straight and Steady: this combo is effective for players trying to earn stars in the solo campaign. You have negative four times negative 100, so that's Going to be equal to negative four times eight plus two times eight minus 18. I just input it into the function, so h of eight is Launch and it will give me the height, so eight secondsĪfter launch, I know I have maximum height. Remember that's what thisįunction does, you give me any x value, any elapsed time after Then, we just have to evaluate what h of eight is, h of eight. When x is equal to eight, eight seconds after launch. The previous question that we reach our maximum height Maximum height that the rocket will reach? Once again, pause the videoĪnd try to answer that. Seconds the rocket is at its maximum height. ![]() Two, which is going to be equal to eight. Negative two plus 18 divided by two gets us what? That's going to be 16 over Just have to go halfway between negative two and 18, so let's do that. To zero when x is either equal to 18, so that is x is equal to 18 or x is equal to negative two, so that is x is equal to negative two. What this x-value is and what this x-value is. You your x value the time after launch, when you'reĪt your maximum height. Value and this x value, the average of the two will give You're going to hit your maximum height right over hereīetween your two zeros or between the two times Gonna have a parabola that looks something like this, Particular and it's going to look something like this, if you're Well, the key realization here is if you have a curve, if you have a parabola in Next question, how many secondsĪfter being launched will the rocket reach its maximum height? Pause the video again and see 18 seconds after launch, we see that our height is zero, we have hit the ground. You get x is equal to 18, so 18 seconds after launch, well we're going forward in time. Then this entire expression "could be equal to zero." X minus 18 equals zero, ![]() Then, we could also thinkĪbout, "Well, x minus 18 if "that's equal to zero, Number of seconds after the launch, so a negative When x is equal to negative two, but remember x is the To zero, then this equation would be satisfied. Well, negative four can't beĮqual to zero, so we could say x plus two equals zero. You get this to be equal to zero is if at least one of these three Of three different things being equal to zero, the way X equal to zero, so zero is equal to negative four times x plus two times x minus 18. To figure out the x when our height is equal to zero. Seconds after launch, how many seconds that's x, so we want The rocket to hit the ground? That means that the height isĮqual to zero, so if you want to figure out how many Launch will the rocket hit the ground? Pause this video again and This is going to be positive 72 times two, which is 144, so 144 meters. To be negative eight times negative 18, negativeĮight times negative 18, which is the same thing as negative eight times negative nine times two. Which is just going to be two times zero minus 18, To negative four, negative four times zero plus two, Just have to go back to this expression and replaceĪll the xs with zeros. "Well, what is h of zero?" To figure out h of zero, we X is equal to zero, they're essentially saying, Seconds after the launch, so at the time of launch, x ![]() Well, what is x at the time of launch? Well, x is the number of Now, the first thing theyĪsk us is what is the height of the rocket at the time of launch? Pause the video and see if Negative four times x plus two times x minus 18. Its height in meters, x secondsĪfter the launch is modeled by h of x is equal to Told a rocket is launched from a platform.
