Physics

A projectile of mass m = 5kg is thrown upward vertically with avelocity v0 = 9 m/s

a) Starting with Newton's 2nd Law FNet = ma,calculate the time to an accuracy of four decimal places at whichthe maximum height is reached when no air resistance ispresent.

b) Starting with Newton's 2nd Law FNet = ma,calculate the time to an accuracy of four decimal places at whichthe maximum height is reached when considering the following forceof air resistance:

Fair = 7.775 x 10-5v

c) Starting with Newton's 2nd Law FNet = ma,calculate the time to an accuracy of four decimal places at whichthe maximum height is reached when considering the following forceof air resistance:

Fair = 0.055v2
