Jaylen is a championship runner of the school's track team. during one of his trials, his speed was measured at 15.1 m/s. find jaylen's kinetic energy during that trial if his mass is 54.6 kg.

Kinetic energy of any moving object = (1/2) (mass) (speed)²

Jaylen's KE = (1/2) (54.6 kg) (15.1 m/s)²

KE = (27.3 kg) (228.01 m²/s²)

KE = 6,224.7 kg-m²/s²

KE = 6,224.7 Joules

That may sound like a lot of KE.  But Jaylen's speed of 15.1 m/s is almost 50% faster than Usain Bolt's average speed for his world's record in the 100 meters, so you'd naturally expect amazingness from Jaylen.

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 .

we need to know the time interval during which the force acts. impulse of force = momentum change
