3sqrt(45) simplifies to: 3sqrt(9 * 5) 3*sqrt(9)*sqrt(5) 3*3*sqrt(5) 9sqrt(5) which equals about 20.1246
and for part a I realized that it is 0 because the particle is at the origin and I have to find the angular momentum of the particle about the origin: a = vi x= r r = 0
My apologies The "following locations" a) at the origin b)at the highest point of its trajectory c)just before it hits the ground the dimensions of angular momentum: ? kg*m^(2)/s the picture is simply a parabola, a projectile launched with some angle theta
