3 of 103 of 10 Items Question As shown below, an object with a mass of 5 kg is moving at a speed of 10 m/s. Another object with a mass of 10 kg is moving at a speed of 5 m/s. Which of the objects has higher kinetic energy? (1 point) Responses The 5 kg object has higher kinetic energy. The 5 kg object has higher kinetic energy. The 10 kg object has higher kinetic energy. The 10 kg object has higher kinetic energy. Both objects have zero kinetic energy. Both objects have zero kinetic energy. The objects have equal kinetic energy.

Answer 1

The formula to calculate kinetic energy is KE = 1/2mv^2, where m is the mass and v is the velocity (speed).

For the first object with a mass of 5 kg and a speed of 10 m/s:

KE1 = 1/2 * 5 kg * (10 m/s)^2 = 250 J

For the second object with a mass of 10 kg and a speed of 5 m/s:

KE2 = 1/2 * 10 kg * (5 m/s)^2 = 125 J

Therefore, the 5 kg object has higher kinetic energy than the 10 kg object.
