Answer:

The value is
$F = 235.2 \ N$

Step-by-step explanation:

From the question we are told that

The mass of the sled is
$m = 80 \ kg$

The coefficient of friction is
$\mu = 0.30$

Generally the force that must be applied to the sled is equal to the frictional force experienced by the sled which is mathematically represented as

$F = m * \mu * g$

=>
F = 80 * 0.30 * 9.8

=>
$F = 235.2 \ N$
