b)The haystack changes your momentum over a longer time
because:
We know that,
impulse = force x t = m (v2 - v1)
f = m (v2 - v1)/t
force will be less and u will likely to be safe. Momentum change will be the same in both the cases.
Answer:
pulse = force * time
force = mg = 0.1kg * 10 = 1 N
time = 0.5
pulse = 0.5 f.s
