Question

A 300.0-kg speedboat is moving across a lake at 35.0 m/s. What is the momentum of the speedboat?

A) 10,500 kg m/s2
B) 10,500 kg m/s
C) 5,250 kg m/s2
D) 91,875 kg m/s

Answer 1

Momentum = mass x velocity = 300x35 = 10500Kg-m/s. Option B is correct.

Answer 2

m = 300 kg,
v = 35 m/s
Momentum = m * v = 300 kg * 35 m/s = 10,500 kg m / s
Answer:
A ) 10,500 kg m / s
