Answer:
The magnitude and direction of its angular momentum relative to point is 115.28 kg m²/s.
Explanation:
Given that,
Mass = 2.00 kg
Velocity = 12.0 m/s
Suppose the distance from point O to point p and angle is 8.00 m and 36.9°.
We need to calculate the magnitude and direction of its angular momentum relative to point
Using formula of angular momentum
Where, r = distance from point O to point P
v = speed
= direction
Put the value into the formula
The direction of angular momentum is pointing into the page.
Hence, The magnitude and direction of its angular momentum relative to point is 115.28 kg m²/s.
