Use the formula,

where
is the cart's displacement (from the origin),
is its initial speed,
is its acceleration, and
is time.


Alternatively, since acceleration is constant, we have

That is, we have these two equivalent expressions for average velocity, where
is the cart's final velocity. Solve for
:


Answer:

Explanation:
given,
mass of wheel(M) = 3 Kg
radius(r) = 35 cm
revolution (ω_i)= 800 rev/s
mass (m)= 1.1 Kg
I_{wheel} = Mr²
when mass attached at the edge
I' = Mr² + mr²
using conservation of angular momentum






Answer:
It should fly 8° to west of south at 430km/h
Explanation:
According to the diagram. X components for both velocities must have the same magnitude in order to get the resultant velocity due south.
Solving for α:
α = 8.03°
