Awheel starts from rest with constant angular acceleration of 4.4 rad/s 2 . after 1.1 s, what is its angular velocity? answer in units of rad/s.

For constant angular acceleration, let us use this equation to find the final angular velocity:

Wf = Wi + αΔt

Wf is the final angular velocity

Wi is the initial angular velocity

α is the angular acceleration

Δt is the elapsed time

Given values:

Wi = 0rad/s

α = 4.4rad/s²

Δt = 1.1s

Plug in the values and solve for Wf:

Wf = 0 + 4.4(1.1)

Wf = 4.84rad/s

Round to 2 significant figures:

Wf = 4.8rad/s

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
