To solve the equation 0 = -4.9t^2 + 24t + 3000 for t, we can use the quadratic formula. The quadratic formula states that for an equation in the form of ax^2 + bx + c = 0, the solutions for x can be found using the formula:
x = (-b +/- sqrt(b^2 - 4ac)) / 2a
In our equation, a = -4.9, b = 24, and c = 3000. Plugging these values into the quadratic formula gives us:
t = (-24 +/- sqrt(24^2 - 4(-4.9)(3000))) / 2(-4.9)
Simplifying the equation further yields:
t = (-24 +/- sqrt(576 + 58800)) / -9.8
t = (-24 +/- sqrt(59376)) / -9.8
Now, let's find the square root of 59376:
t = (-24 +/- 243.52) / -9.8
Now we can proceed to find the two solutions for t by adding and subtracting 243.52 from -24:
Solution 1: t = (-24 + 243.52) / -9.8 = 219.52 / -9.8 = -22.41
Solution 2: t = (-24 - 243.52) / -9.8 = -267.52 / -9.8 = 27.34
Therefore, the solutions for t in the equation 0 = -4.9t^2 + 24t + 3000 are t = -22.41 and t = 27.34.
