In most of the usa a typical house’s roof is inclined at an angle of 15 degrees, but in snowy regions a typical roof is inclined at 27 degrees in order to prevent too much snow from building up after a storm. the steeper angle forces the snow to slide off as it accumulates. suppose a ball were placed at the top of each roof and released such that it had a speed of 4.5 m/s when it reached the edge. which roof’s ball would land farther from the house?
given that the height of the edge of the roof is 3.2 m, verify your answer to part a and then calculate exactly how much farther your chosen ball would land. determine the impact velocity, including angle, of the ball which rolled off the steeper roof.
