Question

When Melony dropped her thermoflask off the top of the Spectrum Parking Structure, the object traveled a vertical distance of h in the first second. In terms of h, how far did the thermoflask travel in the third second? (assume the object never hits the ground)

Answer 1

You can always take d(3s) - d(2s) where d = 1/2 gt² and d in the first second was h = g/2 (substituting 1 second). You can then work out what multiple of h the 3rd second displacement is.

You may have learned Galileo's "rule of odds" where the distance fallen increases by odd multiples: h in the first time interval (It doesn't have to be a second), 3h in 2nd interval, 5h in the 3rd interval...
