another 2 dimensional problem :(
The best leaper in the animal kingdom is the puma, which can jump to a height of 11.5ft (3.51m) when leaving the ground at an angle of 43 degress. With what speed, must the animal leave the ground to reach that height?
at first i thought i could find the time it took for the puma to get to it's maximum height by setting V=0 but i don't that's right...
i tried using the equation
change in y=(sin43)Vot-.5g(t^2)
with change in y = 3.51 m
but i don't know how to solve for t or Vo
this question would be so much easier if the question gave the horizontal distance but it doesnt..so what do i do?
