Explanation / Answer

3)     angle of projectile thrown = tan-1(80/120)

                                                   = 33.7 degree

=> distance travelled by projectile in air = sqrt(2242 + 8202 + 2 * 224 * 820 * cos33.7)

                                                                = 1014 ft

4)    here, angle , theta = tan-1(2/8)

                                      =   14.03 degree

         total distance travelled =   sqrt(82 + 22 + 2 * 8 * 2 * cos14.03)

                                               = 9.952   km
