A skydiver begins by free-falling, and then uses a parachute to float the rest of the way to the ground. The relationship between the skydiver's height while free-falling (in m above the ground), t seconds after jumping, is given by h=-1.7t^2+3050. The relationship between the the skydiver's height while using the parachute (in m above the ground), t seconds after jumping, is given by h=-5t+1650. When did the skydiver pull her parachute, and how high above the ground was she when she did this?
