A girl makes a jump in the long jump with an initial velocity of 12 m/s. She leaves the ground at 20 degrees above the horizontal. How far is her jump?

  • physics - ,

    2(V^2/g)*sin20*cos20 = (V^2/g) sin 40

    Her takeoff speed is higher than Usain's Bolt's 100 meter average speed. I find that hard to believe. (Bolt is the world's fastset human)

    The number you should come up with (9.45 meters)will also exceed the women's long jump world record (7.5 meters)
