•A bieyelist makes a trip that consists of three parts, cach in the same direction (due north) along a straight road. During the first part, she rides for 22 minutes at an average speed of 7.2 m/s. During the second part, she rides for 36 minutes at an average speed of 5.1 m/s. Finally, during the third part, she rides for 8.0 minutes at an average speed of 13 m/s. (a) How far has the bicyclist traveled during the entire trip? (b) What is her average velocity for the trip?

A celebrated Mark Twain story has motivated contestants in the Calaveras County Jumping Frog Jubilee, where frog jumps as long as 2.2 m have been recorded. If a frog jumps 2.2 m and the launch angle is 45, find (a) the frogs launch speed and (b) the time the frog spends in the air. Ignore air resistance.

you are driving your car along a country road ar a speed of 23.8m/s. As you come over the crest of a hill, you notice a farm tractor 25.0 m ahead of you on the road, moving in the same direction as you at a speed of 10.0 m/s. You immediately slam on your brakes and slow down with a constant acceleration of magnitude 8.60 m/s^2. how far will you travel before you stop the car?
Two cars given by the king of France and queen of England (let them be named car F and car E) are straightly moving in a line. Their position functions are found to be respectively: z(t) = 14 m - (8m/s^2)t^2 and z(t) = - 50 m - (4m/s^2)t^2. At some point, these fancy and jaw-dropping cars from the said royals meet at about z' = 114 meters. From the given data, find the average velocity of car F from the time intervals t = 0 up to t'. A. - 16 m, B. 16 m, C. 32 m, or D. - 32 m.
