1. The problem statement, all variables and given/known data 1. A 5kg object has a momentum of 15 kg m/s. What is the net force required to accelerate the object to 8 m/s over 15 seconds? A) .35N B) 1.7N C) 5.1 N D) 11 N E) 23 N 2. Relevant equations F=deltaP/deltaT 3. The attempt at a solution So I use that formula (which I am not sure is right). so wouldn't it be mv/t. So, (5)(8)/15 which is 2.67N which is not an answer choice. I think I am using the wrong formula, but it's all I can think of! Please help.
