16 A ball is kicked towards goal posts from a position 20 m from and directly in front of the posts. The ball takes 0.60 s from the time it is kicked to pass over the cross-bar, 2.5 m above the ground. The ball is at its maximum height as it passes over the cross-bar. You may ignore air resistance. a Calculate the ball's horizontal component of velocity b Calculate the vertical component of the velocity of the ball immediately...

Suppose a golfer hits a ball with a velocity of 40 m/s at an angle of 30 degrees to the horizontal. The projectile model can be used to answer some questions about what will happen to the ball later during its flight. a) where will the ball be 2 seconds later? b) what is the greatest height the ball will reach? c) if the golf ball is hit in the direction of a 12 meter tree which is 80 meters...

8.9 An automobile with four wheels is about to pass over a speed bump as shown in the insert in Eigure 8.35a. The velocity of the vehicle at that time is 10 km/h. The vehicle is supported by a suspension system that consists of one coilover per wheel (a coilover is a combination of a shock absorber, or a damper, enclosed by a coil spring). The analytical model of the suspension system is illustrated in Figure 8.35b. The mass of...

MATLAB Grader CONTENTS For this problem you will model a field goal attempt in an NFL football game as a simple projectile motion problem. For a field goal attempt, the ball is snapped seven yards back from the line of scrimmage, where the place holder holds the ball on the ground for the kicker. For a successful attempt, the kicker must kick the ball through the uprights above the cross bar, which is ten feet high and parallel to the...
