This problem will show you how a soccer ball can also be a projectile, and how by knowing a couple of simple things, you can find out everything you need about the problem, including how far and how high the ball traveled in addition to its time of flight.

Oops – I think I may have forgotten that there was a “t” multiplied by the [V sin (theta)] – because the units in the answer don’t work under the sq rt sign, do they? We have “seconds” left in the numerator, not seconds squared. So the correct answer to this problem is actually t = 1.9 seconds (as shown). Just do the entire problem and do not take the square root since you only have a single “t” to solve for. The correct equation before you plug in numbers is: t = 2V sin (theta) / g
At 3:07 in the video what happens to the T term in the equation V sin( theta)T -.5g(T squared)
