Find the tangential component of the acceleration vector at the point (0 , 1 , 1). c. Find the normal component of acceleration. 6. A ball is thrown at an angle of forty ﬁve degrees to the ground. If the ball lands 100 meters away, what was the initial speed of the ball? You may leave your answer in terms of g , acceleration due to gravity. 7. Let f ( x,y ) = x 2 2 x 2y 2 . a. What is the domain of f ? b. Find lim ( x,y ) → (0 , 0) f ( x,y ). Justify your answer with complete details. 1...
