A15.5 kg block is pulled by two forces. the first is 11.8 n at a 53.7 angle and the second is 22.9 at a -15.8 angle. what is the magnitude and direction of the acceleration?

at

Explanation:

We need to calculate the components of the resultant force on both the x (horizontal) and y (vertical) direction.

Components of the first force F1:

Components of the second force F2:

So the components of the resultant force are

So the magnitude of the resultant force is

And the direction is

The magnitude of the acceleration can be found by using Newton's second law:

while the direction is the same as the resultant force, .

need to see circuit to get time constant
