I am really confused on the set up in this answer how do I do it?

A block with mass mp
6.75 kg is suspended on a string. You pull upwards on the string creating a tension force of magnitude
Tyb = 70.9175 N.
If the upward speed of the block is 3.25 m/s right now, then what is its speed 2.5 s later?
Don't know where to start?

Expert Solution
Step 1

Given value---

  • mass = 6.75 kg.
  • tension = 70.9175 N.
  • initial speed = 3.25 m/s.
  • time = 2.5 second .

We have to find---

  • final speed after t time ?
