an 8kg dog is sliding to the right on a frozen pond at 5m/s. suddenly, at the same moment, roy begins pushing the dog to the left and sally pushes the dog to the right.both roy and sally use a force of 16n and there is no friction. a)what is the net force on the dog? b)what is the dog acceleration? c)what will the dog's acceleration? c)what will the dog's velocity be after 4 second of both kids pushing him?

  • physics -

    a) F = 16 - 16 = 0
    b) F/m = 0
    c) This looks like the same question as b
    d) 5 m/s (unchanged)
