Sagot :
The third object has the most kinetic energy (15.49 joule).
We need to know about kinetic energy to solve this problem. kinetic energy can be defined as the energy of moving object. It can be determined by
KE = 1/2 . m . v²
where KE is kinetic energy, m is mass and v is speed of object.
From the question above, we know that:
m1 = 4.4 kg
m2 = 3.0 kg
m3 = 1.6 kg
v1 = 1.6 m/s
v2 = 3.0 m/s
v3 = 4.4 m/s
Find the kinetic energy
KE1 = 1/2 . m1 . v1²
KE1 = 1/2 . 4.4 . 1.6²
KE1 = 5.632 joule
KE2 = 1/2 . m2 . v2²
KE2 = 1/2 . 3. 3²
KE2 = 13.5 joule
KE3 = 1/2 . m3 . v3²
KE3 = 1/2 . 1.6 . 4.4²
KE3 = 15.49 joule
Hence, the third object has the most kinetic energy (15.49 joule).
