A ball is kicked upwards the equation h(t)=-5t^2+40t describe the height in meters after t seconds. When you fill in the table don’t stop until the height is again at zero

Just finished at t = 1.234 got height = approx. 41.75 m
starting at t = 1.235

This is going to take forever!!

so h=0 at t=0 and at t=8

so keep going, and you'll finish up at
