The maximum speed with which you can throw a stone is about 25 m/s. can you hit a window 50 m away and 13 m up from the point where the stone leaves your hand? what is the maximum height of a window you can hit at this distance?

no, the maximum height = 12.3m

Explanation:

The equation for the trajectory of the ball for a given angle can be derived from:

(1)

and

(2)

Combining equation 1 and 2:

(3)

Taking the derivative:

(4)

Setting equation 4 equal to zero to calculate the maximum angle:

(5)

Plugging equation 5 back into equation2 confirms, the trajectory can't reach the target. The maximum height is 12.3m.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
