0 Question 2 v A projectile is fired horizontally to the west at a velocity of 41 m/s. What is the absolute value of the horizontal velocity (and the direction; East or West) of the projectile after 3 seconds? V = unit Direction: What is the magnitude of the vertical velocity of the projectile after 3 seconds? V = unit Direction: 0 Question 3 v A projectile is thrown at an angle with a velocity of 32 m/s. What is the vertical velocity of the projectile at the top of its flight? V = unit Does it have a horizontal velocity? | Select an answer V| What is the vertical acceleration of the projectile at the top of its flight? a = unit _> A ball is kicked horizontally off of a cliff. The the kick is rightward, at a speed of 25 meterslsecond, and the cliff has a height of 140 meters. Please round all answers to whole numbers (no decimal places). 1. How far, horizontally (from the base of the cliff) does the ball land? 2. What is the downward speed (vertical only) of the ball when it strikes the ground? 3. What is the overall speed of the ball (both \"x\" and \"y\" components, so use Pythagorean theorem) when it strikes the ground? 4. Suppose that instead a steady gust of wind was blowing near the cliff directly opposite of the ball's initial motion we can reasonably model the added air resistance (drag) caused by this wind as a purely horizontal component. Suppose this horizontal (\"x\") acceleration of 0.5 meterslsecondZ in the opposite direction as the initial velocity. How far horizontally does ball land now? 0 Question 6 v A toad travels 24 cm across a flat surface with a single jump. (a) If the toad jumps at an angle 25 degrees from the ground, what is its takeoff speed? Please use three significant figures, and don't round when you do the calculations on your calculator. (b) What is its horizontal speed? 0 Question 7 v Hint 1 Olympus Mons on Mars is the largest volcano in the solar system, at a height of 23.5 km and with a radius of 314 km. If you are standing on the summit, with what initial velocity would you have to fire a projectile from a cannon horizontally to clear the volcano (you wish for it to land exactly one radius away) and land on the surface of Mars? Note that Mars has an acceleration of gravity of 3.7 m/sz. \"m 2 m/s .Question9 v11 1 Dara and Cameron are studying projectile motion in their physics lab class. They set up a Pasco projectile launcher on the edge of their lab table, so that the ball will be launched at an initial height of H = 31.0 inches, initial velocity of 30 = 5.8 mls and an initial angle of 90 = 54 (see diagram). They can then record the landing location by placing a piece of carbon paper on the floor some distance away from the launcher. When the ball lands, it will make a mark on the carbon paper. a) Find horizontal component of initial velocity (two significant figures please). :] b) Find vertical component of initial velocity (two significant figures please). :1 c) Find the maximum height of the motion (two significant figures please). :] cl) Find the landing location on carbon paper (three significant figures this time). :] 0 Question 10 v A baseball is thrown from the outfield to home plate. Let's say the outfielder and catcher are 49.2m horizontally apart, and the ball leaves the outfielders hand at a height of 2.41 m. (Assume no air resistance) Part A) If it takes 1.855 for the ball to get from fielder to catcher, what was the magnitude of the velocity of the ball in the "x" right before the catcher gets the ball? VX = unit' ' Part B) If the catcher catches the ball at a height of 1.65m, find the vertical velocity the ball had when it left the fielders hand. VyO = unit' Part C) At what angle (in degrees) did the fielder throw the ball with respect to the ground? angle =
