So here we need to calculate the magnitude of the force massive the sled or the object Whatever. Maybe twelve, one thousand two hundred twelve and ten kilograms. And we know that the acceleration must be one point two zero meters per second squared. Ah, we know that Sigma half in the ex direction is going to equal thie only ten on ly the force tension and this issue can equal the mass times acceleration. So the force tension needed that need is going to be one thousand two hundred ten kilograms times one point two Media stress second squared and this is giving us one thousand four hundred and fifty two. Nunes, this is the required force tension. That is the end of the solution. Thank you for watching.
