1. The problem statement, all variables and given/known data A stone is thrown at 30 m/s. what is the widest river it can be thrown across? (the stones ends at the same vertical height from where it was thrown) 2. Relevant equations x=vxot y=vyot + 0.5gt2 3. The attempt at a solution i know i need to find t first. using the second equation i got t as 5.2s. when i multiplied 5.2s by vxo (30m/s) i got 156.3 m but the answer should be 92m. wat did i do wrong?
