Question

EXAM Kinematics, Vectors Problem 1. Let's go to the circus! An UniverSoul Circus acrobat is fired by a cannon at an initial speed of 15 meters per second (m/s) at an angle of 0 40° above the horizontal as shown in the figure (not to scale) below At a distance of 20 meters away, her partner is standing on a platform at a height of h meters. At the instant that the acrobat is launched, her partner throws a basketball towards her horizontally at an initial speed of 5 m/s . Ignore air resistance in solving this problem also, since the figure is not drawn to scale, ignore grid values of the axes in the figure a) (40 points) Write equations for the horizontal and vertical positions as functions of time for both the acrobat and the basketball b) (40 points) When will the performer and basketball be located at the same HORIZONTAL position? c) (20 points) Find the value of h for which the acrobat will catch the ball Assume that she and the ball must be at the same height for her to catch it. d) EXTRA CREDIT (20 points) Find the magnitude of the velocity of the
