I’m almost positive this is correct.
Answer:
0.8764kgm/s
Explanation:
Finding the velocity(v) before it hits the ground , where g is 9.8m/s²
v²= u² + 2gh
v² = 0 + 2× 9.8 × 2
v² = 40
v = √39.2
=6.26m/s
momentum= mass × velocity
= 0.14 × 6.26
= 0.8764kgm/s
C) corrosive, should be your best answer
hope this helps
