a steam engine of mass 3 x 10^4 kg pulls two wagons each of mass 2 x 10^4 with an - Science - Force and Laws of Motion

Question

a steam engine of mass 3 x 10^4 kg pulls two wagons each of mass 2
x 10^4 with an acceleration of 0 2 m/s^2 calculate the (i) force
exerted by the engine (ii) force experienced by each wagon

Vara · Accepted Answer

(i)Force=Total mass×acceleration         =3×104+2×2×104×0
2         =14000 N(ii)Force experienced by the first wagon after the engine:F1=2ma    = 2×2×104×0
2     =8000 NForce experienced by the second wagon after the engine:F2=ma    =2×104×0
2    =4000 N

a steam engine of mass 3 x 10^4 kg pulls two wagons each of mass 2 x 10^4 with an acceleration of 0.2 m/s^2. calculate the (i) force exerted by the engine (ii) force experienced by each wagon.
