tennisball mashine shoots a ball straight up in the air, it lands after 7 seconds What's the hight of the ball given v=f(t)=30-10t i figured that the equation i got is actually the derivative of -5t^2+30t ball shots upp with a velocity of 30m/s, is a physics mix i have no pheta angle neede to solve it in a simpler way...vertex apex im asked: what does 30 stand for? -10t?acceleration? and what's max height? i have a graf with and dowsslopping linear line crossing the y axis at 30m/s and the x axis at 3 seconds
