I don’t know how to find the angular velocity with what i’m given

We define angular velocity ω as the rate of change of an angle. In symbols, this is ω=ΔθΔt ω = Δ θ Δ t, where an angular rotation Δθ takes place in a time Δt. The greater the rotation angle in a given amount of time, the greater the angular velocity. The units for angular velocity are radians per second (rad/s).

hope this helps ^-^

pe = weightxheight = 2000x1000=2,000,000joules

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
