Question

Two ropes are attached to a 40-kg object. The first rope applies a force of 25 N and the second, 40 N. If the two ropes are perpendicular to each other, what is the resultant acceleration of the object?

Answer 1

1.2 m/s^2

Step-by-step explanation:

I will ignore gravity and friction....and will choose 25 N as UP and 40 N to Left (see diagram)

Resultant force: R^2 = 25^2 + 40^2 R = sqrt(2225)=47 N

F = ma

F/m = a

47 N / 40 kg = a = 1.2 m/s^2
