An arrow is fired upward with an initial speed of 38 m/s. What is it's maximum height? How long does it take to return to the ground? How high is it at 1.3 seconds? How high at 3.8 seconds?
x = Vo*t + .5*a*t^2
y = .5gt^2
The Attempt at a Solution
I got 73.75 m for the maximum height, 7.76 s for the time to return, 41.11 m at 1.3 seconds and 73.64 m at 3.8 seconds (which is basically the maximum height). Am I correct?
