السلام عليكم ورحمه الله ...

عندي اسئله فيزياء بسيطه ....(بالنسبة الكم طبعا)

ممكن اتساعدوني في حلها لو سمحتو ...

Problem 2
A 2 .00-kg object undergoes an acceleration given by
a = 2.00ˆ i + 5.00ˆ ( j )m/ s2
Find the resultant force acting on it and the magnitude of the resultant force.
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?

F=ma
F= 4.00 i + 10.00 j
