Several objects were dropped from a balcony. Using the data below, determine which statements must be true regarding the rate of force of each falling object. Neglect (ignore) air resistance. Object Mass Diameter Height of drop Tennis Ball 0.06 kg 6.6 cm 5 m Baseball 0.15 kg 74 cm 5 m Bowling Ball 5 kg 21 cm 5 m Golf Ball 0.04 kg 4.3 cm 5 m Statement 1: All balls hit the ground at the same time Statement 2: All balls hit the ground with different forces Statement 3: The bowling ball hit the ground first and the tennis and golf ball hit the ground last Statement 4: It is not possible to tell how much force each ball hit the ground with

statement three and statement 2

Explanation

since they are weighted different, they will have more or less force (more mass=more force), also the heavier an object, the greater its acceleration while falling.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
