1. The problem statement, all variables and given/known data Jill throws a Javelin by first accelerating it from rest through 85 cm and releasing it from a height of 2.2 m at an angle of 35 degrees and it goes a distance of 62 m. A) What are the values of the vertical and horizontal components of initial velocity? B) Find the following: X-initial position, Y-initial position X-final pos., Y-final pos. X-velocity initial, X-velocity final Y-velocity initial, X-velocity final Acceleration in x and y direction and t-final for X and Y C) What is the magnitude of the impact velocity vector? D) What is the impact angle? 2. Relevant equations I'm sure I have missed one: V=(ds/dt) a= (Vf-Vi)/(tf-ti) x(t)=xi + (Vx)(t) y(t)=yi + (Vy)(t) - (1/2)gt^2) 3. The attempt at a solution I started writing down all my known terms and have the following from the given info: Xi = 0 Yi = 2.2m ax = 0 ay = -g = 9.8m/s^2 Yf = 0 Xf + 62 Theta = 35 degrees At this point I went to plug known values into the x(t) and y(t) equations to find unknowns. The needed unknowns I see now are velocity and time of impact. I am completely stumped on the next step to take from here to find velocity or time of impact. Any help would be appreciated.
