1. Consider a projectile, say a frictionless teddy bear, which is thrown at an angle of theta with an initial

velocity of v0.

a) For a fi xed angle, and the maximum height of the teddy bear.

b) Calculate the distance that the teddy bear travels before returning (gently, of course) to the

ground (which is assumed to be

at).

c) Use these pieces of information to nd the angle which produces the maximum of the sum of height and distance.

usage of function. in these question.
