If a long jumper at the top of his trajectory is moving at 6.5 m/s (horizontally) and his centre of mass is 1.1m abover where it was when he launched into the jump, how fast must he have been moving when he launched?
Vx = Vox + ax*t
The Attempt at a Solution
In all texts i look at they say that the initial velocity should be the same as final velocity in the x-axis but that isn't the correct answer for the question in the text.
Thanks for any help.
