Question

question 1 of 10 you slide across home plate during a baseball game. if you have a mass of 82 kg, and the coefficient of kinetic friction between you and the ground is 0.45, what is the force of friction acting on you? a. 804 n b. 362 n c. 451 n d. 621 n

Explanation:

Step1: Calculate normal force

The normal force $N$ on a flat - surface is equal to the weight $mg$. Given $m = 82$ kg and $g=9.8$ m/s², $N = mg=82\times9.8 = 803.6$ N.

Step2: Calculate frictional force

The formula for kinetic frictional force is $F_f=\mu_kN$, where $\mu_k = 0.45$ and $N = 803.6$ N. So $F_f=0.45\times803.6 = 361.62\approx362$ N.

Answer:

B. 362 N
