Question

How much momentum will an object of mass 5kg transfer to the floor if it falls from a height of 2m?

Answer 1

Answer:

momentum p = 14 × 5 ^ 1/2

Explanation:

Given mass m = 5kg

height h = 2m

we know that momentum(p) = mass(m) × velocity (v)

now to find the velocity (v) = (2gh)^1/2

v = (2×9.8×2)^1/2

= 14 × (5)^1/2 / 5

ie. (14 × square root of 5 divided by 5)

Now the momentum... , p = 5 × 14 × 5^1/2 / 5

= 14 × 5 ^1/2 .
