... Assume that the three blocks in the figure move on a frictionless surface and that a 42N force acts as shown on the 3.0kg block. Determine (a) the acceleration given this system, (b) the tension in the cord connecting the 3.0kg and the 1.0kg blocks, and © the force exerted on the 2.0kg block by the ...

"Horse and Wagon Problem"?
... Consulting the diagram, notice that there are now two forces acting on the wagon. The net force on the wagon equals the force the horse exerts minus the friction force the ground exerts. If the horse pulls harder on the wagon than the friction force, there will be a forward-pointing net force, and t ...

Solution
... A freight train consists of two 8.00 104 kg engines and 45 cars with average masses of 5.50 10 4 kg . (a) What force must each engine exert backward on the track to accelerate the train at a rate of 5.00 10 –2 m/s 2 if the force of friction is 7.50 105 N , assuming the engines exert identica ...

This means that there is only a 65% chance of them being different, not enough to say that the difference is significant. The results for partners 1 and 2 in method B differ by about 1.5 standard deviati ...
