Question

A football player at practice pushes a 80 kg blocking sled across the field at a constant speed. The coefficient of kinetic friction between the grass and the sled is 0.30. How much force must he apply to the sled

Answer 1

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`
