Consider a 10.0 kg projectile launched with an initial speed of 100m/s,
at an elevation angle of 35.0度.
The resistive force is given by R=-bv, where b=10.0 N.s/m
(1)Use a numerical method to determine the horizontal and vertical
coordinates of the projetile as function of time.
(2)What is the range of this projectile??
(3)Determine the elevation angle that gives the maximum range for the projec

除暴安良是我們作市民的責任，行善積德是我本人的興趣，
所以扶老太太過馬路我每個星期都做一次，
如果是碰到國定假日的話，我還做兩、三次呢！
