Answer: m= 2.16 kg
Explanation: Momentum is expressed in the following formula:
p = mv
Derive to find m:
m = p / v
= 4.75 kg.m/s / 2.2 m/s
= 2.16 kg
Cancel out m/s and the remaining unit is in kg.
P = density × gravity acceleration × height
P = 1200 × 9.81 × 15/100
P = 1765.8
I believe that the answer is A but correct me if i’m wrong
