iv) what is the velocity of the shell when it hits the ground? v) is the ball accelerating or decelera

Answer the following. Thank you!

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.

y = 25 m/s 35 -20 m 1. As a volcano erupts, one particular lava rock is projected from the mouth of the volcano at 35 degrees above the horizontal, calculate: a. The lava rock's total time in the air. b. Total horizontal distance traveled of the lava rock. c. The rock's final total velocity.
