I need help with these problems:

1. A 3.9 kg object is subjected to two forces, F1= (2.8N)i + (-4N)j and F2= (3.7N)i + (-10.4N)j. The object is at rest at the origin at time t= 0.

a) What is the magnitude of the object's acceleration?Got That one.

b) What is the magnitude of the velocity at t= 3.8 s?Got that one too.

c) What is the magnitude of the object's position at t= 3.8 s?No idea how to do this one.

2. A 1.5 kg particle starts from rest and moves a distance of 2.3 m in 2.9 s under the action of a single, constant force. Find the magnitude of the force.

Please!! Can someone help me asap!!
