What is the momentum of a 500-kg car, moving at 10 m/s, going 20° north of west direction? a. 5000 kg m/s b. (4698i+1710j) kg-m/s c. (-4698i+1710j) kg-m/s d. (1710i+4698j) kg-m/s

Step 1
Momentum (p) is the product of mass (m) and velocity (v). So, p = m*v = 500 kg * 10 m/s = 5000 kg m/s. This is the magnitude of the momentum. However, the question also asks for the direction. The car is moving 20° north of west. In physics, we often break down Show more…
