Answer :
Final answer:
The velocity of an object with a momentum of 40 kgm/s and a mass of 60 kg is 0.67 m/s.
Explanation:
To find the velocity of an object with given momentum and mass, we can use the formula:
Momentum = Mass x Velocity
Given that the object's momentum is 40 kgm/s and its mass is 60 kg, we can rearrange the formula to solve for velocity:
Velocity = Momentum / Mass
Substituting in the given values, we get:
Velocity = 40 kgm/s / 60 kg = 2/3 m/s = 0.67 m/s
So the correct answer is D. 0.67 m/s.
