## Homework Statement

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

## Homework Equations

F=deltaP/deltaT

## 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.
