For which situation do you think the cannon ball will go father: if it is set at a 25-degree angle, or if it is set at a 35-degree angle? (1 pt) Hypothesis: Concluslons: 2) Set the cannon to have an initial speed of 20 m/s20 \mathrm{~m} / \mathrm{s}. For which situation do you think the cannon ball will go father: if it Is set at a 60-degree angle, or if it is set at a 70-degree angle? (1 pt) Hypothesis: Conclusions: 3) Set the cannon to have an initial speed of 15 m/s15 \mathrm{~m} / \mathrm{s}. For which situation do you think the cannon ball will go the highest: If it is set at a 25-degree angle, or if it is set at a 35-degree angle?

For which situation do you think the cannon ball will be in the alr for the longest time: if it is set at a 25-degree angle, or If it is set at a 35-degree angle? (1 pt) Hypothes/s: Conclusions: 6) Set the cannon to have an initial speed of 15 m/s15 \mathrm{~m} / \mathrm{s}. For which situation do you think the cannon ball will be in the air for the longest time: if it is set at a 60-degree angle, or If it is set at a 70 -degree angle? (1 pt) Hypothesis: Conclusions:

Studdy Solution
For v0=15m/s v_0 = 15 \, \text{m/s} and angles 60 60^\circ and 70 70^\circ : - Calculate T60=2×15×sin(60)9.8 T_{60} = \frac{2 \times 15 \times \sin(60^\circ)}{9.8} - Calculate T70=2×15×sin(70)9.8 T_{70} = \frac{2 \times 15 \times \sin(70^\circ)}{9.8}
Compare T60 T_{60} and T70 T_{70} .
For each scenario, use the calculations to form hypotheses and conclusions based on the results.
