DONT ANSWER IF YOU DONT KNOWWW PLEAS A golfer hits a ball and gives it an initial velocity of 40 m/s , at an angle of 30 degrees above the horizontal.
a. How long did the ball stay in the air?

b. How far horizontally did the ball travel before hitting the ground?

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
