A stone is thrown vertically upward with an initial velocity v0. The distance travelled in time 4v03g is
2v023g
v023g
v022g
5v029g
Time of ascent is v0g given time is 4v03g time for downward journey is 4v03g-v0g=v03g distance travelled in v03g while falling =12gv03g2=v0218g so total distance travelled is v0218g+v022g= 5v029g
