Doug is driving a golf ball off the tee. his downswing takes 0.50sec from the top of the swing until ball impact. at the top of the swing, the club's angular velocity is zero; at the instant of ball impact, the club's angular velocity is 30rad/s. the swing moment of inertia of the club about the grip is 0.220kg*m^2. what average torque does doug exert on the golf club during the downswing? a. 13.2 b. 26.4 c. 64.6 d. 106.8

Which component of the earth’s atmosphere is decreased due to photosynthesis?

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
