Respuesta
The tangential velocity of Robert is approximately 2.05 m/s.
Explicación
## Step 1The problem involves calculating the tangential velocity of Robert, who is running around a circular track. The formula for tangential velocity is given by:###
where
is the velocity,
is the distance, and
is the time.## Step 2The distance
is the circumference of the circular track. The formula for the circumference of a circle is given by:###
where
is the circumference and
is the radius of the circle.## Step 3Substitute the given radius
into the formula for the circumference to find the distance
.## Step 4Substitute the calculated distance
and the given time
into the formula for velocity to find the tangential velocity.
