Homework Statement A projectile is fired with an initial speed of 16.0 m/s at an angle of 45.0^\circ above the horizontal. The object hits the ground 9.00 s later. What is the direction (below +x) of the projectile's velocity at the instant it hits the ground? Vo=16m/s a=-g θ=45 Tf=9...

yeah that's what I got

I finnaly figured it out...thank you guys for the guidence

what I meant to say is my answer wasnt going to help me sorry for the unclarity

sorry I didnt see that question...I am not sure the only thing I can think of is time final-time initial but that wouldn't help me. I really don't knowfrom what I can think of it would equal the velocity over the gravity

I know this book and website combination is not the most helpful thing in the world. Whaat I have done so far is pluged in Hmax for the Xf of the second kinematic equation and when I solved it I ended up getting v_0^2/g-1/2 v_o^2 which got me to where it said I was close but I was either missing...

the maximum value of h for which a collision occurs before the first ball falls back to the ground?

how to find h_max

This problem has been giving me problems for the past two days and I can't figure it out :( please help. this is my first ever physics class. Homework Statement A rubber ball is shot straight up from the ground with speed v_0. Simultaneously, a second rubber ball at height h directly above the...
