While you are on lookout duty at your fortress, you spot an enemy ship moving directly towards you with a constant speed of 15 m/s. At the moment when the ship is 1.5 km away, you fire a shell at an angle of 45 degrees above the horizontal, which hits the enemy ship. What was the initial speed of the shell to 2 sig figs?

An army captain wants to fire an artillery shell deep into the enemy's flank. However, he knows that there are strong winds blowing above at height H that would blow his shells off course. If his artillery fires shells with muzzle velocity Vo, what Is the farthest that he can fire them without their going off course?

-20. Two cyclists, Mike and Josh, simultaneously started toward each other from two towns d = 24 km apart. Josh rode at vj = 25 km/h, and Mike %3D at UM = 15 km/h. The moment they start, a fly also starts from Josh towards Mike and after reaching Mike, immediately returns towards Josh. The fly continues back and forth motion between the cyclists till the cyclists meet. Air speed of fly is UF = 30 km/h and the wind blows always towards Mike with a constant velocity u = 10 km/h. Find the total distance s flown by the fly. Sneedometer shows speed and odometer shows distance travelled, both
