Answer 1

Heres the problem please help :

A ball is thrown up at 20m/s on a roof of a building 30m high. Find the highest height of the ball, and the time it takes to hit the ground.

Answer 2

PUT dv/dt in for acceleration thus making f=dv/dt x M possibly use -cv for drag force then if i remember correctly you integrate from o to to v or 0 to t possibly both on on each respective side. then rearrange the formulae to get V(t)= or t=.
