July 9, 1988, to set the women's world record. Assume
that she launched the discus with an elevation angle of
45°, and that her hand was 2.0 m over the ground at the
instant of launch. What is the initial speed of the discus
required to achieve that range? (Neglect any effects due

- You can use any coordinate system you like to solve a projectile motion problem. To demonstrate the truth of this statement, consider a ball thrown off the top of a building with a velocity v at an angle with respect to the horizontal. Let the building be 50.0 m tall, the initial horizontal velocity be 9.00 m/s, and the initial vertical velocity be 12.0 m/s. Choose your coordinates such that the positive y-axis is upward, the x-axis is to the right, and the origin is at the point where the ball is released, (a) With these choices, find the balls maximum height above the ground and the time it takes to reach the maximum height. (b) Repeat your calculations choosing the origin at the base of the building.arrow_forwardIn a game of American football. a quarterback takes the ball from the line of scrimmage. runs backward a distance of 10.0 yards, and then runs sideways parallel to the line of scrimmage for 15.0 yards.
