How much momentum will a dumbbell of mass 10kg transfer to the floor if it falls from a height of 80cm?

Given, Mass = 10kg
Height, S = 80cm = 0.8m
g = 10m/s²
By the third equation of motion, we can get velocity,
v² = u² + 2gS
→v² = 2 × 10 × 0.8 = 16 = 4m/s
So, velocity = 4m/s
Now Momentum = mass × velocity
So, →10 × 4 = 40kgm/s
