I need serious help with the step-by-step process on how to solve this problem:

The speed of a bobsled is increasing, because it has an acceleration of 3.42 m/s². At a given instant in time, the forces resisting the motion, including kinetic friction and air resistance, total 659 N. The mass of the bobsled and its riders is 252 kg. (a) What is the magnitude of the force propelling the bobsled forward? (b) What is the magnitude of the net force that acts on the bobsled?

Expert Solution

Step 1

Given :

The acceleration of the bobsled, $a = 3.42 m / s^{2}$

Net forces resisting the motion, $f_{R} = 659 N$

Mass of the bobsled and its riders, M = 252 kg

Determine

a) the magnitude of the force $(F_{x})$ propelling the bobsled forward.

b) the magnitude of the net force $(F_{n e t})$ acting on the bobsled.
