A stone falls from a train trestle The stone's height in meters above the ground is modeled by the function h(t) = -4.9+2 + 155 where t is time in seconds. To the nearest tenth of a second, how long does it take the stone to hit the
ground? State what strategy you will use to answer the question, and then find the answer. (1 point)
Solve the equation - 4.9t? + 155 = 0 for t using the Square Root Property. The stone will hit the ground
in 56 seconds
O Solve the equation - 4.9t+ 155 = 0 for t by factoring. The stone will hit the ground in 5.6 seconds.
Solve the equation -4.9t? + 155 = 0 for t using the Square Root Property. The stone will hit the ground
in 58 seconds
O Solve the equation -4.9+2 + 155 = 0 for t by factoring. The stone will hit the ground in 5.8 seconds.
