Homework Statement
A particle is thrown in the angle pi/3 radian with speed 10m/S. Find the time of movement if the maximal height is equal to the distance of fall.
Homework Equations
v^2-voy^2=2gh
The Attempt at a Solution
0-10^2*3/4=2*10*hmax
hmax=3.75
v0x*2t=3.75
v0*cos60*2t=3.75
10*0.5*2*t=3.75
t=0.375. The answer in my book is 1S.
I also want to know why whe I use the formula of maximal height v0^2sin^a/2g and maximal fallL=v0^2sin2a/g with the data from the problem they don't come out to be equal.
