Answer:
The net force acting on the bobsled is 300 N.
Explanation:
Given:
Mass of the bobsled is,
Displacement is,
Initial speed is, m/s
Final speed is, m/s
Net acceleration acting on the bobsled can be determined using the following Newton's equation of motion:
Plug in all the given values and solve for acceleration, .
Now, as per Newton's second law, net force is the product of mass and acceleration. So,
Therefore, the net force acting on the bobsled is 300 N.
