Respuesta
The tangential velocity of Robert is approximately 8.06 m/s.
Explicación
## Step 1The problem involves calculating the tangential velocity of Robert, which is the speed at which he is running around the circular track. The formula for tangential velocity is given by:###
where
is the tangential velocity,
is the radius of the circular path, and
is the time taken to complete one lap.## Step 2In this problem, the radius
is given as 2.13 m and the time
is given as 1.31 s.## Step 3Substitute the given values into the formula to calculate the tangential velocity.
