3. The radar tracking an airplane gives the coordinates of the plane as r(t) and 0(t). At some instant of time, 0 = 40° and r = 6400 ft. From successive measurement of r and 0, the first derivatives at this instant are estimated as r=312 ft/s, Ô= 0.039 rad/s2, and the second derivative, f=9.67 ft/s?, = 0.003807 rad/s?. Calculate the velocity and acceleration of the airplane at this instant. r()

v sin 20 gives the distance x travelled (in feet) by a projectile launched from 32 The formula r% = the ground, with initial velocity v (in feet/sec) and initial angle 0 (in radians or degrees). a. Write an expression for the total differential in x. b. Use the total differential to estimate the error in calculating the range of a projectile with initial velocityv 100 ft/sec and initial angle 0= 50 degrees, with measurement errors of dv = t10 ft/sec (for velocity) and d6==5 degrees (for the initial angle). (Note: remember to use radians for the differential in 0.)
