Question

What is the velocity of an 72 kg skateboarder traveling down hill with a momentum of 1800 kg-m/s.
25 m/s
50 m/
1296 m/a
18 m/s

Answer 1

Answer:

25 m/s

Explanation:

Momentum = mass × velocity

Given that,

• momentum = 1800 kgm/s
• mass = 72kg

velocity  = Momentum ÷ mass

velocity = 1800 ÷ 72

velocity = 25 m/s
