المشاركة الأصلية كتبت بواسطة رورو2 Problem 3 Three forces, given by F1 = −2.00ˆ i + 2.00ˆ ( j )N, F2 = 5.00ˆ i − 3.00ˆ ( j )N, and F3 = −45.0ˆ ( i )N, act on an object to give it an acceleration of magnitude 3 m/s2. (a) What is the direction of the acceleration? (b) What is the mass of the object? (c) If the object is initially at rest, what is its speed after 10 s? (d) What are the velocity components of the object after 10 s?
