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.

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
