Using Engineering Mechanics Dynamics Sample Problem No. 11.7, write a program that demonstrate the use of conditional loop, generate a table of time, x, y, and plot the outputs (time vs y and x vs y) Reference: Vector Mechanics for Engineers - Dynamics, Beers, Johnston, Eisenburg, Mazurek ISBN-13 9780077402327 (Tenth Edition), McGraw Hill Sample 11.7 A projectile is fired from the edge of a 150-m cliff with an initial velocity of 180 m/s at an angle of 30° with the horizontal. Neglecting air resistance, find (a) the horizontal distance from the gun to the point where the projectile strikes the ground, (b) the greatest elevation above the ground reached by the projectile 180 m/s (v), = (180 m/s) sin 30° = +90 m/s a=-9.81 m/s 30° 150 m The vertical and the horizontal motion will be considered separately Vertical Motion. Uniformly Accelerated Motion. Choosing the positive sense of the y axis upward and placing the origin O at the gun, we have r, = 90-9811 180 /s 30° 150 m y=90+49012 Eq. 3 Horizontal Motion. Uniform Motion Choosing the positive sense of the x axis to the right, we have 180 m/s (v),-(180 m/s)cos30° = +155.9 m/s 30
