A volleyball is hit when it is 4 ft above the ground and 12 ft from a 6-ft-high net. It leaves the point of impact with an initial velocity of 40 ft/sec at an angle of 28° and slips by the opposing team untouched. The acceleration due to gravity is g= 32 ft/sec?. Answer the following questions. a. Find a vector form for the path of the volleyball. r(t) = i+ (Do not evaluate. Do not include the degree symbol in your answer.)

Express v and w in terms of their magnitudes and direction angles. b). Find the resultant vector, v + w. c). The magnitude of v + w, called the ground speed of the plane, gives its speed relative to the ground. Approximate the ground speed to the nearest mile per hour. d).
