A toy dart gun generates a dart with a momentum of 140 kg*m/s and a velocity of 4 m/s. What is the mass of the dart?*

35 kg

Explanation:

From the question,

Momentum (I) = mass (m) × velocity (v)

I = m×v Equation 1

Where m = mass, v = velocity

make m the subject of the equation

m = I/v Equation 2

Given: I = 140 kgm/s, v = 4 m/s

Substitute these values into equation 2

m = 140/4

m = 35 kg

Hence the mass of the dart is 35 kg
