3: Astronauts on Mars were bored one day, so they decided to see how long it would take a Martian to fall back to the surface if they threw one straight up into the air! The height of the Martian, in m, meters, is given by the
equation: h= -8t2 + 32t , where t is the time in seconds.
A: Find how long it takes for the Martian to hit the surface?
B: Find out the time taken for the Martian to be 24 meters in the air.
