NOTE: ONLY DETERMINE r(t) and (t) for t=1,16, and 31s. The position as a function of time (x(t),y(t)) of a projectile fired with a speed of v0 at an angle is given by x(t)=v0costy(t)=v0sint21gt2 where g=9.81m/s2. The polar coordinates of the projectile at time t are (r(t),(t)), where r(t)=x(t)2+y(t)2 and tan(t)=x(t)y(t). Consider the case where v0=162m/s and =70. Determine r(t) and (t) for t=1,6,11,,31s
