You shot a gun straight up into the air with a velocity of 500 m/s. How long will it take beforeit hits the ground again?
You shoot a gun with a initial velocity of 500 m/s horizontally at the exact instant you drop arock from exactly the same height (at 1.6 m off of the ground). Which one will hit the ground first.
Rock 1000 0.5
Pillow 200 10
Bottle of soda 2000 2
Loaf of bread 100 1
Answer:
The densest materials are rock and bottle of soda.
Explanation:
The density of material is given by,
Density =
Case 1: Rock
Density =
Density = 2000
Case 2: Pillow
Density =
Density = 20
Case 3: Bottle of soda
Density =
Density = 1000
Case 4: Load of bread
Density =
Density = 100
The densest materials are rock and bottle of soda.
