Answer:
θ = 25.4º
Explanation:
For this exercise we can use the projectile launch equations, let's use the scope ratio
R = vo² sin 2θ / g
For the first ball
R1 = 35² 2 sin (2 30) /9.8
R1 = 108.25 m
For the second ball, they ask that the second ball fall in the same place, so the horizontal distance is the same
R2 = R1
Therefore we calculate the angle
sin 2θ = R1 g / vo²
sin 2θ = 108.25 9.8 / 37²
sin 2θ = 0.7749
2θ = sin⁻¹ (0.7749)
2θ = 50.8º
θ = 25.4º
Explanation:
there are 4 phases in which matter could be classified.
1. Solid: an example of this would be the metal copper.
2. Liquid: an example of this would be H2O or water.
3. Gas: an example of this would be oxygen gas or O2
4. Plasma: an example of this would be lightning.
