A stone is thrown vertically upward with an initial speed of 15.7 m/s. Neglect air resistance. Calculate the velocity of the object when it first reaches a height of 9.77 meters.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

pretty sure it's false

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
