1.What is the required intersection sight distance for all 3 design vehicles for through, right and left movements for a 2 lane minor road that stops for a 5 lane, 2 way major road? The speed limit is 45 mph and this intersection is located near a major university and there are many pedestrians. The grade for the major road is 4% and 3% for the minor road.

2.A crate has a weight of 50 lb and is acted upon by a force having a variable magnitude of P=20t, where p is in pound and t is in seconds. compute the crates velocity two seconds after P has been applied. The crates initial velocity is 3 ft/s down the plane of 30 degrees, the coefficient of kinetic friction is uk=.3.
