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 .
