Answer :
Final answer:
The student's momentum is 1966.57 kg·m/s.
Explanation:
The student's momentum can be calculated using the formula:
Momentum = Mass x Velocity
Given that the student's mass is 122 lb, which can be converted to kilograms by dividing by 2.2046 (since 1 kg equals 2.2046 lb), the mass of the student is approximately 55.34 kg. The velocity of the student just before hitting the water is 35.575 m/s².
Using the formula, the student's momentum can be calculated as:
Momentum = 55.34 kg x 35.575 m/s²
= 1966.57 kg·m/s
