A Honda Civic travels in a straight line along a road. The car's distance x from a stop sign is given as a function of time I by the equation x(1) = at - Br. where a = 1.50 m/s and B = 0.0500 m/s. Calculate the average velocity of the car for each time interval: (a) = 0 to i = 2.00 s; (b) != 0 to = 4.00 s; (c) = 2.00 s to t = 4.00 s. A watermelon is dropped from the edge of the roof of a build- ing and falls to the ground. You are standing on the pavement and see the watermelon falling when it is 30.0 m above the ground. Then 1.50 s after you first spot it, the watermelon lands at your feet. What is the height of the building? Neglect air resistance. During a storm, a car traveling on a level horizontal road comes upon a bridge that has washed out. The driver must get to the other side, so he decides to try leaping the river with his car. The side of the road the car is on is 21.5 m above the river, while the opposite side is only 2.0 m above the river. The river itself is a raging torrent 57.0 m wide. (a) How fast should the car be traveling at the time it leaves the road in order just to clear the river and land safely on the opposite side? (b) What is the speed of the car just before it lands on the other side?
