Course: Physics copy 1

Q: Using a muzzle velocity of 10 m/s, investigate the relationship between launch angle $$\theta$$ and the range, R). Which relationship best fits the data you have collected?
- $$R =10.2 \cdot sin(2 \theta)$$
- $$R =9.8 -(\theta-20)^2$$
- $$R =9.8 -(\theta-10)$$
- $$R =sin(\theta)\cdot10$$
- $$R=-(\theta-45)^2 \cdot10+10$$
A: $$R =10.2 \cdot sin(2 \theta)$$

Q: Using a muzzle velocity of 12 m/s, investigate the relationship between launch angle $$\theta$$ and the range, R). Which relationship best fits the data you have collected?
- $$R =14.69 \cdot sin(2 \theta)$$
- $$R =9.8 -(\theta-24)^2$$
- $$R =sin(2\theta)\cdot144$$
- $$R =sin(\theta)\cdot12$$
- $$R=cos(\theta)\cdot12$$
A: $$R =14.69 \cdot sin(2 \theta)$$

Q: Using a muzzle velocity of 14 m/s, investigate the relationship between launch angle $$\theta$$ and the range, R). Which relationship best fits the data you have collected?
- $$R =20 \cdot sin(2 \theta)$$
- $$R =9.8 -(\theta-28)^2$$
- $$R =9.8 -(\theta-14)$$
- $$R =sin(2\theta)\cdot196$$
- $$R=cos(\theta)\cdot14$$
A: $$R =20 \cdot sin(2 \theta)$$

- $$R =9.8 -(\theta-32)^2$$
- $$R =sin(2\theta)\cdot256$$
- $$R=cos(\theta)\cdot16$$
- $$R=-(\theta-45)^2 \cdot16+10$$
A: $$R =26.12 \cdot sin(2 \theta)$$
