Answer:
The angular momentum of the particle is 58.14 kg m²/s along positive z- axis and is independent of time .
Explanation:
Given that,
Mass = 1.70 kg
Position vector
We need to calculate the angular velocity
The velocity is the rate of change of the position of the particle.
We need to calculate the angular momentum of the particle
Using formula of angular momentum
Where, p = mv
Put the value of p into the formula
Substitute the value into the formula
Hence, The angular momentum of the particle is 58.14 kg m²/s along positive z- axis and is independent of time .

Explanation:
given,
diameter of the balloon = 30 m
density of the air = 1.10 Kg/m³
weight of the balloon and cargo = ?
density of the surrounding air = 1.20 kg/m³
we know,
Density = mass/volume
m = density x volume
m = 16964.6 Kg
Weight of the balloon
W = m g
W = 16964.6 x 9.81
W = 166422.729 N
Weight of the balloon and the cargo is equal to W = 166422.729 N
