[SOLVED] Drawing a Y vs Time Graph in a projectile motion problem 1. The problem statement, all variables and given/known data A snowball rolls off a barn roof that slopes downward at an angle of 40 degrees. The edge of the roof is 14.0m above the ground, and the snowball has a speed of 7.00 m/s as it rolls off the roof. Ignore air resistance. Draw y-t graphs for the motion in part A. 2. Relevant equations y=(Vo*sin(alpha))*t-1/2*g*t^2 (In this problem alpha is 40) 3. The attempt at a solution I've tried inserting various time intervals (i.e. .1 sec; .2 sec; .3 sec; etc) to the equation above (I assumed that y= the distance fallen from 14m at the specific time t). So the resultant y I calculated, I subtracted from 14m to get the resultant y coordinate at time t. This being an online assignment, requires exact (y,t) coordinates starting from 0 seconds-1.3 seconds having 0.1 second increments in between. The y coordinates are also specific to 0.1 m increments ranging from 0.0 meters to 14.0 meters. Any possible help would be greatly appreciated. Thanks!
