2 Problem Norm the Niner throws up a football with a speed v0 = 10 m/s and at an angle relative to the vertical on a windy day. The wind affects the football by creating a horizontal acceleration of 0.7 m/s² to the left (the wind has no vertical acceleration). At what angle must the ball be thrown so that its path forms a loop and returns to Norm? Assume no drag acts on the football. [Hint: because the football follows a "loop" the velocity profile will be antisymmetric, such that the veloc- ity vector at the end (when catching the ball at some time T) is the negative of the velocity vector when initially throwing the ball. There is a particular angle 0 that makes this true. You should also review your trignometric identities, since one is needed for this problem.] Ao vo WIND

![2 Problem
Norm the Niner throws up a football with a speed v0 = 10 m/s and at an angle relative to the
vertical on a windy day. The wind affects the football by creating a horizontal acceleration of 0.7
m/s² to the left (the wind has no vertical acceleration). At what angle 9 must the ball be thrown
so that its path forms a loop and returns to Norm? Assume no drag acts on the football.
[Hint: because the football follows a "loop" the velocity profile will be antisymmetric, such that the veloc-
ity vector at the end (when catching the ball at some time T) is the negative of the velocity vector when
initially throwing the ball. There is a particular angle 0 that makes this true. You should also review your
