What equation was substituted into both sides of equation (1) to solve the problem?
What equation was substituted into both sides of equation (1) to solve the problem?
- Δy = v0t - ½gt2 (correct)
- Δy = v0t + ½gt2
- Δy = v0t + ½gt2
- Δy = v0t - ½gt2 + θ
What is the correct rearranged form of the equation (v01 - v02 - 1.15g)t2 = -(1.15v01 - 0.66125g)?
What is the correct rearranged form of the equation (v01 - v02 - 1.15g)t2 = -(1.15v01 - 0.66125g)?
- t2 = (1.15v01 + 0.66125g) / (v02 - v01 + 1.15g)
- t2 = -(1.15v01 - 0.66125g) / (v01 - v02 - 1.15g)
- t2 = (1.15v01 - 0.66125g) / (v02 - v01 - 1.15g) (correct)
- t2 = -(1.15v01 + 0.66125g) / (v01 - v02 - 1.15g)
