Question

a ball is fired at 3 degrees (pi/60). At 12.6 meters out, it is at its apex, .33m above its starting height. Gravity is present and the ball experiences no other acc or air resistance. What is the original velocity? I got 56.121 but it seems wrong a ball is fired at 3 degrees (pi/60). At 12.6 meters out, it is at its apex, .33m above its starting height.

Answer 1

it seems right to me

Answer 2

when i put it in projectile motion simulators they give me different numbers on practically everything, i am not new to physics and this should be quite simple yet i cant see what i did wrong

Answer 3

I mean, it should be really high shouldn't it? how much different was it?

Answer 4

they only allowed me to put in velocity, angle, and mass/size. i got max heights of .44 and times of .6 when the height is GIVEN as .33 and i calculated the total time as .449

Answer 5

meters and seconds**

Answer 6

ah... mental death. I dont know sorry. I've been doing an internal assessment for IB for 6 hours today, so im kinda not as usful as I should be. sorry man

Answer 7

harsh haha ill just assume that the physics simulators use physics engines and not actual newtonian physics XD
