Net Force
What is the magnitude of the net force on the bobsled?
A 75kg bobsled is pushed along a horizontal surface by two athletes. After the bobsled is pushed a distance of 4.5m starting from rest, its speed is 8m/s. Find the magnitude of the net force on the bobsled.
Please show the work. Teacher isn't helping very much.
Let me give it a try....
I got 532.5 Newtons, see if you get the same answer I do; I am not sure this is right.
I used the kinematics equation: Vf^2=2ad+Vi^2, to find the acceleration which was 7.1 m/s^2. Next I used this equation: sigma F=ma, to find the applied force on the bobsled. (f=(75kg)(7.1)). I disregarded the force of friction though.....
