Can you help me solve for the rest of the problems

Projectile Motion Worksheet 1. Florence Griffith-Joyner of the United States set the women's world record for the 200 m run by running with an average speed of 9.37 m/s. Suppose Griffith-Joyner wants to jump over a river. She runs horizontally from the river's higher bank at 9.37 m/s and lands on the edge of the opposite bank. If the difference in height between the two banks is 2.00 m, how wide is the river? 2. The longest shot on a golf tournament was made by Mike Austin in 1974. The ball went a distance of 471 m. Suppose the ball d= 471. was shot horizontally off a cliff at 80.0 m/s. Calculate the height of the cliff. = 4 Hm h7 y - som/s v = at And time - 5:89 to dy = ? d = yat? V : (9.8 5. 8 ) = - 57, 7 a = - 9.8 m/s' d= /2 (-9.8) (5. 89) =169.99 3. Recall Elmer Trett, who in 1994 held the speed record for an arrow being shot by a bow. If the arrow is in flight for 1.23s, how high above the bulls-eye must he aim? 4. The longest stuffed toy ever manufactured is a 420 m snake made by Norwegian children. Suppose a projectile is thrown horizontally from a height half as long as the snake and the projectile's horizontal displacement is as long as the snake. What would be the projectile's initial speed? 5. Libyan basketball player Suleiman Nashnush was the tallest basketball player ever. His height was 2.45 m. Suppose Nashnush throws a basketball horizontally from a level equal to the top of his head. If the resultant speed of the basketball is 12.0 m/s when it lands, what was the ball's initial speed? (Hint: Consider the components of final velocity.) - 2.45m V=12.dmis V = ? 9.75in u = at : 0.71 find time ..2. * a2+b = cz atb = ca d = 1 2 at 2 d s /2 ( - 9 . 8 ) + 2 a2 + ( - 6 - 96 2 ) = 123 Y = 12nil a = - 9.8 mb ? 2. 45 2- 4. 9t + 2 (124 46.983 + 95: 56 do 2. 45 m - 4.9 - 4. 9 : 50.5 15-(071)1 = 19. 78 mls 6. The world's largest flowerpot is 1.95 m high. If you were to jump horizontally from the top edge of this flowerpot at a speed of 3.0 m/s, what would your landing resultant velocity be
