(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An object was lauch at uknow velocity at an angle of 70 degree in the X direction. After 4 second later it land. The distance was 800 meter. Find the Vo of the object. What Vo is compose of?

2. Relevant equations

t= 4 sec

distance travel= 800

angle= 70

3. The attempt at a solution

x= Vocos(u)T and T= 2VoSin/g

X/(cos(u)*t)= Vo

the twon Vo did not match is there any other way to find the solution
