Paul wants to jump his car over 45 barrels. Each barrel is 1m wide. If he takes off horizonally from a ramp that is 5.5 m higher than where he will land, how fast does he need to drive to clear the barrels?
Paul needs to go
mis to clear the barrels ( Give answe to the hundreths place)

h = -5.5 = 1/2 g t^2    distance he will fall in time t

t = (11 / 9.8)^1/2      using 9.80 m/s^2 for g

t = 1.06 sec

So Vx = 45 m / 1.06 s = 42.47 m/s

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

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 .
