A rhinoceros is at the origin of coordinates at time t1=0. For the time interval from t1 to t2 = 10.0 s , the rhino's average velocity has x-component -3.2 m/s and y-component 4.5 m/s .

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 .

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
