• ### when a ball is tossed into the air, the height, h, in metres, of the ball after t seconds is modelled by?

h= 5t²+20t+1. After how many seconds, correct to two decimal places, does the ball hit the ground?

I was wondering, is this correct?

h= -5 (t²-4t) +1

h= -5 (t²-4t+4-4) +1

h= -5 (t-2)² +21

Let h=0

0= -5 (t-2)² +21

√-21/-5= t-2

t= 4.05

Therefore the ball hits the ground at apprximately 4.05 seconds.
