  • How come when you was calculating the acceleration, you took into account the resistive forces of BOTH vehicles but then when you was calculating the tension in the rope considering one vehicle, you ignore the resistive force of the the other?

  • @Cesariono I don't like to ignore questions like this but it is a good question, not easy to answer in the written word. But. Listen again and I say, for finding the acceleration I consider the lorry and car as one unit, which as long as the tow rope remains taut and does not stretch, it IS one unit. But for part (b) I consider ONLY the forces acting on the car, OR ONLY the forces acting on the lorry. Not sure if this helps. But best I can do in written word. Mathstutor.

  • cheers mathstutor. ive got my m1 exam 2morrow so this was useful as clarification, because i did these questions b4 u did and then checked if they were right and they all were, so im pleased now 4 2morrow :D! i just wanted 2 know if u hav any c4 vids up because i hav that on the 15th of june and i find that a lot harder :(

  • All the video clips free on youtube can be viewed via my web site, plus you could consider the full versions on dvd that are available at mathstutorDOTcom

  • is the DVD available in other countries? I know all the maths methods and theorems are the same, but the exams and papers would be very different.

  • All my dvd's are available worldwide. For outside UK there is an addidtion £2 shipping charge, this is a one off charge no matter how many items in an order. Visit mathstutorDOTbiz for all details. Look forward to hearing from you. mathstutor.

see all

  • This is so very helpful! thank you so much!!!

  • I'm taking Mechanics soon. This was really helpful to get an idea about mechanics. I like it. I kind of enjoyed it while you were solving it, I'll be sure to check your tutorials. Thank you!!

  • @mathstutorbiz No, that makes sense! When you treat the bodies as a single body, F = ma can be applied. Thank you very much.

  • @r0bbi3rulez LMFAOOO funni geeza.... jesus u knw!! hahaha
