A boy pulls a train at a 40-degree angle from horizontal with a force of 2.00N with an engine and caboose. The caboose m = 100g and engine m = 150g (engine in front). The coefficient of friction is 0.330. What is the force of tension in the string between the engine and caboose?

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048

v patient student

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
