- They came between two buildings that are separated horizontally by a distance of 3.6m and a drop of 2.8m. To cross safely, Jerry has to jump in the horizontal direction with a minimum speed ?0. (a) Calculate the minimum speed ?0 Jerry needs to cross safely. Tom jumps with a speed of 4.8 m/s at an angle of 45⁰ (wow!!! Looks like Tom knows physics). (b) Where does Tom land? (Please show work) (c) By how much does Tom clear the gap? (d) What is Tom’s velocity (magnitude and direction) on landing.Christopher watches a stick float downstream in a river and notices that it moves 15 m [El in a time of 2.5 x 10' s. His friend, John, is starting on the south side of the river and is going to swim across. In still water, John knows that he can swim with a speed of 1.2 m/s, relative to the water. a) What is John's velocity relative to the shore? b) If the river is 1.5 km wide, how long will it take John to cross the river? c) How far downstream will be land?A treasure hunter follows a map moving 25 km [N], 37 km [W 37 degrees S], 63 km [E 65 degrees S] and finally 15 km [N 17 degrees E].

- 16. A bullet is fired horizontally from a rifle and hits a target that is 150 m away. If the bulletlanded 15 cm below the point at which the marksmen aimed, how fast was the bullet travelling?2. Your friend is on the top of a sheer vertical cliff 14 meters high and you are on the ground below. Your friend throws a ball at an angle of 49° above the horizontal, and with an initial speed of 9.2 m/s. How long is the ball in the air? How far from the base of the cliff should you be in order to catch the ball1? Neglect air resistance. (The situation is as shown in Fig. 6.3.) 3. Starting from rest, a 62 g ball rolled down the tube like the one to be used during this experiment and stopped exactly at the exit. The initial and final ends of the tube were 109 Ocm and 101 cm above the floor, respectively. What was the frictional energy loss? If the tube is rotated so that the heights of the ends of the tube are now 124 cm and 88 cm above the floor, what is the exit velocity of the ball? 4.
