[grade 12 momentum -physics questions need assisance with 6.3][1]

How to calculate the final velocity of a body given two graphs of two objects of net force versus time [1]: https://i.stack.imgur.com/u7UZq.jpg

  • 1. Welcome to Stack Overflow. 2. Please look at our [help section](https://stackoverflow.com/help); this question is unacceptable. 3. The problem (or the part that you have shown us) does not provide enough information to determine the answer. – Beta Jan 30 '22 at 02:26
  • I’m voting to close this question because it is appears to be a homework problem with no sign of effort toward a solution. – Beta Jan 30 '22 at 02:28
  • I have attempted this question with al means possible ..have tried to use the conservation of momentum , or create simultaneous equations of impulse before and after collision ..i assumed there is a collison since Fnet changes direction for object Q – Nkosi Ncube Jan 30 '22 at 16:53
  • This is a high school question but i went further to try and integate to get velocity as a function of time to know use – Nkosi Ncube Jan 30 '22 at 16:54
  • Conservation of momentum doesn't help, because we know nothing about the thing imparting a force on the object. We can calculate the momentum imparted to the object, but without knowing the *mass* of the object, we cannot calculate the acceleration. And even if we knew the change in velocity, we do not know the initial velocity, so we cannot calculate the final velocity. – Beta Jan 30 '22 at 16:59
  • I’m voting to close this question because it's a physics question, not a programming question. Check out [the physics stackexchange](https://physics.stackexchange.com/) – Joundill Feb 01 '22 at 20:43

In 6.1 you have calculated the total impulse p for Q. To get from impulse to velocity you can use the definition of impulse: p = mv. Therefore you need the mass m of the object Q, which seems not be given. With the data given the answer would be:

final velocity = v = 60 / m in m/s
