Question

In a dream, Dr. O'Brien imagined that the previous super bowl had a slightly
di erent outcome. In the last drive, the Patriots were in eld goal range, and since
it was a HUGE eld goal, the NFL agreed if made, it would count for 6 points,
enough to win the game. Sadly, the eld goal post was 61m away, and 10m high to
the crossbar. Dr. O'Brien steps out on to the eld and is capable of making this
kick, provided his calculations are correct. He knows that with the proper kick, he
could barely hit the crossbar and make the ball go over, and the time of
ight he
estimated in his dream was 3.3 seconds. Find the magnitude and the direction of
the initial velocity in Dr. O'Brien made the successful kick, and was later drenched
in gatorade by a very happy, World Champion patriots team.

Explanation / Answer

actual dispalcement R^2 = x^2 + h^2

R^2 = 3.3^2 + 61^2

R = 61.1 ,

so

speed V = 61.1/3.3 = 18.5 m/s
