{'kinetic energy': [0, 0, 4, 7], 'object': [1, 0, 11, 43], 'speed': [0, 1, 2, 0], 'mass': [0, 0, 2, 3]}

To find the speed at which the object is moving, we can use the equation for kinetic energy: KE = (1/2)mv^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity or speed.

Given that the object has a mass of 2000 g (or 2 kg) and a kinetic energy of 100 J, we can plug these values into the equation and solve for v:

100 = (1/2)(2)(v^2)

100 = v^2

v^2 = 100

v = √100

v = 10 m/s

Therefore, the object must be moving with a speed of 10 m/s.

Option 1: 10-0 m/s - This is the correct answer. The object is moving with a speed of 10 m/s.

Option 2: 11 1 m/s - This option does not match the calculated speed of 10 m/s.

Option 3: 11-2 m/s - This option does not match the calculated speed of 10 m/s.

Option 4: 12-1 m/s - This option does not match the calculated speed of 10 m/s.

Therefore,
