Answer:
100 J
Step-by-step explanation:
The formula for kinetic energy is as follows:

where
KE= kinetic energy (J)
m= mass (kg)
v= velocity (m/s)
Given: m= 50 kg, v= 2 m/s
Substituting the given information into the formula:
KE
= ½(50)(2²)
= ½(50)(4)
= 100 J
Answer:
108
Step-by-step explanation:
The cubes has a volume 1/27 because 1/3 *1/3 *1/3 =1/27. Now we just take 4 and divide by 1/27. Which equals 108 cubes.
