Question

rob colley set a record in “pole sitting” when he spent 42 days in a barrel at the top of a flagpole with a height of 43 meters, suppose you wanted to throw him up a sandwich. with what speed do you have to throw the sandwich up so that it would just reach the barrel?

Answer 1

v^2 = 2as = 19.6 * 43 = 842.8
v = 29.03 m/s
check:
h = 29.03t - 4.9t^2
the vertex is at (2.96,43)
