A ball of mass m is thrown vertically upward .Air resistance is not negligible.Assume the force of air resistance has magnitude proportional to the velocity,and direction opposite to the velocity's direction .At the higest point , the ball's acceleration is
1. zero
2. less than g
3. equal to g
4. greater than g

Dear Student,



Regards.

  • 6
Equal to zero it is because only when the v at that point is 0 only g acts on it, as irrespective of velocity g is constant
  • 5
Also the acceleration at the highest point is constant and the only value that is found constant in that situation is g thus a=g
  • 0
Equal to zero
  • -1
