no.3 please with explanation A Honda Civic travels in a straight line along a road. Thecar's distance x from a stop sign is given as a function of timeI by the equation x(1) = at - Br. where a = 1.50 m/s andB = 0.0500 m/s. Calculate the average velocity of the car foreach 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 seethe watermelon falling when it is 30.0 m above the ground. Then 1.50 safter you first spot it, the watermelon lands at your feet. What is theheight of the building? Neglect air resistance.During a storm, a car traveling ona level horizontal road comes upon a bridge that has washed out. Thedriver must get to the other side, so he decides to try leaping the river withhis car. The side of the road the car is on is 21.5 m above the river, whilethe opposite side is only 2.0 m above the river. The river itself is a ragingtorrent 57.0 m wide. (a) How fast should the car be traveling at the timeit leaves the road in order just to clear the river and land safely on theopposite side? (b) What is the speed of the car just before it lands on theother side?

Solution: (a) Calculate the height of fall. h=21.5-2 m=19.5 m The horizontal distance to be covered…
