Question

two motorcycles are moving through an intersection. the kinetic energy of each motorcycle depends on the motorcycles mass and speed.
motorcycle | mass (kg) | speed (m/s) | kinetic energy (hj)
black motorcycle | 304 | 20 | 608
red motorcycle | 304 | 5 | 38
compare the two motorcycles.
the black motorcycles mass is the red motorcycles mass.
the black motorcycles speed is the red motorcycles speed.
the black motorcycles kinetic energy is the red motorcycles kinetic energy.

Explanation:

Step1: Compare Mass

The mass of the black motorcycle is 304 kg, and the mass of the red motorcycle is also 304 kg. So, we check if they are equal.
$304 = 304$

Step2: Compare Speed

The speed of the black motorcycle is 20 m/s, and the speed of the red motorcycle is 5 m/s. We check the relationship between 20 and 5.
$20 > 5$

Step3: Compare Kinetic Energy

The kinetic energy of the black motorcycle is 608 hJ, and the kinetic energy of the red motorcycle is 38 hJ. We check the relationship between 608 and 38.
$608 > 38$

Answer:

The black motorcycle's mass is equal to the red motorcycle's mass.
The black motorcycle's speed is greater than the red motorcycle's speed.
The black motorcycle's kinetic energy is greater than the red motorcycle's kinetic energy.
