Question

The speed of a bobsled is increasing, because it has an acceleration of 3.54 m/s'. At a given instant in time, the forces resisting the motion, including kinetic friction and air resistance, total 598 N. The mass of the bobsled and its riders is 283 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?

Answer 1

The magnitude of the force propelling the bobsled forward is 1002.82 N. The magnitude of the net force acting on the bobsled is 598 N.

Step-by-step explanation:

To determine the magnitude of the force propelling the bobsled forward, we need to use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration.

In this case, the acceleration is 3.54 m/s² and the mass is 283 kg. So, the force propelling the bobsled forward is:

Force = mass * acceleration

= 283 kg * 3.54 m/s²

= 1002.82 N

The magnitude of the net force that acts on the bobsled is equal to the sum of the forces resisting the motion. In this case, it is given that the total force resisting the motion is 598 N. So, the magnitude of the net force is:

Net force = total force resisting motion

= 598 N
