Two forces F1 = -7.50i + 6.00j and F2 = 8.40i + 7.50j are acting on a mass of m = 6.20 kg. The forces are measured in newtons. What is the magnitude of the object's acceleration?

Question

Can you show me step by step? I'm trying to study for an exam.

Answer 1

Just add the forces to get the resultant force

f = 0.9i + 13.5j

Since F = ma,
a = f/m = 0.9/6.2 i + 13.5/6.2 j
= 0.145 i + 2.177 j

|a| = 2.18
