Part A The ball at A is kicked with a speed v4 = 16.5 ft/s and at an angle 0A= 30°. Assume the ground has the shape of a parabola as shown in (Figure 1). Determine the coordinates of the point where the ball strikes the ground. Enter the z and y coordinates of the point separated by a comma using three significant figures. VO AX i rec ? z, y= ft Submit Request Answer

SOLVE CAREFULLY!! Please Write Clearly and Box the final Answer for Parts A-D, with THE CORRECT UNITS) Thank you. Express your answer to three significant figures and include appropriate units. Use images below

Typed solution will get downvote. please provide handwritten answer if not possible for you then leave it to others.

A pendulum with a cord of length r = 1.05 m swings in a vertical plane (see figure). When the pendulum is in the two horizontal positions 0 = 90° and 0 = 270°, its speed is 4.95 m/s. a (a) Find the magnitude of the radial acceleration (in m/s2) for these positions. m/s2 (b) Find the magnitude of the tangential acceleration (in m/s?) for these positions. m/s? (c) Draw a vector diagram to determine the direction of the total acceleration for these two positions.
