The force on an object is described as a function of time equation:

F(t) = 3t^2+7t

What is the impulse delievered by the force over a period of time from 0 to 5.0s? What is the average force exerted on an object over this time period? If the object has a mass of 2.0kg and is initally at rest, what is the velocity of the object at 5.0s?
