Question

In an exciting game, a baseball player manages to safely slide into second base. The mass of the baseball player is 88.1 kg and the coefficient of kinetic friction between the ground and the player is 0.50. find the magnitude of the frictional force?

Answer 1

Answer:

$f=431.69\ N$

Explanation:

Given:

• mass of the player, $m=88.1\ kg$

• coefficient of kinetic friction between the ground and the player, $\mu_k=0.5$

• Since the normal reaction force on the player due to its mass will be equal to the weight of the player.

We have the expression of kinetic friction as:

$f=\mu_k.N$

here:

N = normal reaction force

$f=0.5\times (88.1\times 9.8)$

$f=431.69\ N$
