Asprinter accelerates from rest to 10.0 m/s in 1.30 s. what is her acceleration in km/h^2?

as you know answer of acceleration  in ms⁻² = 7.6

change ms⁻² into km h⁻²

= 1m / s² (1)

1 m change int kg

= 0.001 km / s²

As  s² = ( 1 /  3.6 ˣ 10³ h )²

so put values in ... (1)

=  0.001 km /    ( 1 /   1.296 ˣ  10⁷ h)

=  0.001 km ˣ 1.296 ˣ 10⁷ / h²

=   12960 km h⁻²

=    12960 km h⁻² / ms⁻² ˣ 7.6ms⁻²

ms⁻² cecel on both sides

= 12960 km h⁻² ˣ 7.6

= 98496 km h⁻²

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 .
