- Professional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o. The duration of the impact of the club and ball has been measured to be 1.00 ms. c) Find the average force exerted by the club on the ball. d) Find the average shear deformation of the club's 0.800 m long and 1.00 cm diameter steel shaft.Find the maximum height of this projectile provided with this equationpls all

Dancer A fired the ball with a mass of 0.05 kg with an initial velocity 15 m/s at an angle 35° above the x-axis (neglect the air resistance). Find the total time the ball is in the air.Calvin throws a ball straight down from the balcony of an apartment building at a velocity of 5.04 m/s.
