- 1. The position and velocity for one-dimensional motion can be derived from the following equations: 1 Xf – Xị = Vịt +,at? 2 Vf = Vị + at Where, x; is the initial position, Xf is the final position, v; is the initial velocity, vf is the final velocity, a is the acceleration, and t is the time. Modify the above equations for the motion of free fall object. [Hints: Definition of free fall object: An object that is falling under the sole influence of gravity is called a free-falling object.]1. A projectile is thrown with a speed of 100 ft/s in a direction 30 degrees above the horizontal. Illustrate the projectile motion and answer the following: a. How many feet will it rise? b. How many feet will the maximum horizontal displacement be?3.) You throw a ball straight up. The ball leaves your hand at a height of 2.00 m above the ground with a speed of 20.0 m/s (~45 mph). Ignore air resistance and use g = 10.0 m/s2 to answer the following questions. You can use a spreadsheet but show your sample calculations. 3a.) Calculate the height, y(t), and velocity, vy(t), at 0.50 second intervals until the ball hits the ground. Show your results in a table and put the units in the column headers: t (s), vy (m/s), y (m). 3b.) Use this data to draw a motion diagram for the ball at 0.50 second intervals. Label the height and the speed at each time interval. Label the origin, starting height, maximum height, and final height. Include the velocity vectors for each time and location of the ball. 3c.) Calculate the time it takes for the ball to hit the ground and the final velocity of the ball just as it hits the ground. Include this velocity vector in your diagram.
