Two forces F1 = 3H and F2 = 4H are applied to one body. The angle between the force vectors is 90 degrees.

Two forces F1 = 3H and F2 = 4H are applied to one body. The angle between the force vectors is 90 degrees. What is the acceleration of a body if its mass is 1 kg?

Since the forces act perpendicular to each other, their resultant is defined as the hypotenuse of a right-angled triangle built on these forces:

F = √F1² + F2² = √9 + 16 = √25 = 5

2) According to Newton’s second law, we obtain that

F = ma

a = F / m

a = 5/1 = 5 m / s²
