A 93.4 kg cross country skieron snow has lk 0.0995. Withhow much force must he pushto accelerate at 0.550 m/s??(Unit = N)

The force required to push the mass in terms of acceleration is,
[tex]F=ma[/tex]where m is the mass of the body and a is the acceleration.
As the force of friction is acting on the body,
The value of force of friction here is,
[tex]F^{\prime}=\mu_kmg[/tex]where g is the acceleration due to graviity,
Substituting the known values,
[tex]\begin{gathered} F^{\prime}=0.0995\times93.4\times9.8 \\ F^{\prime}=91.07\text{ N} \end{gathered}[/tex]Thus, the force required to accelerate the body to the acceleration a is,
[tex]F-F^{\prime}=ma[/tex]Substituting the known values,
[tex]\begin{gathered} F-91.07=93.04\times0.55 \\ F=142.242\text{ N} \end{gathered}[/tex]Thus, the force that push the body to the acceleration
