Two forces act on a object with different magnitudes and direction

AI Thread Summary
To determine the acceleration of a 48 kg object acted upon by two forces, one measuring 65N at 59° from the x-axis and another at 35N at 32° from the y-axis, vector addition is essential. The forces must be broken down into their components using trigonometric functions (sine and cosine) to find the resultant force. Once the total force is calculated, apply Newton's second law, F = ma, to find the object's acceleration. Understanding the vector nature of forces is crucial for solving this problem. Properly calculating the components will lead to the correct acceleration value.

Homework Statement


Two forces act on a 48 kg object. One force has magnitude 65N directed 59° clockwise from the positive x-axis and the other has a magnitude 35N at 32° clockwise from the positive y-axis. What is the magnitude of this object's acceleration?



Homework Equations


F = ma
and there's prob more equations...

The Attempt at a Solution


I really do not know how to solve this one. I know you need to use the angles and cos and sin somewhere but I am really confused. Help?!

Hi qtgrl120! Welcome to PF! :smile:

Forces are vectors, so use vector addition (or just add the components) to find the total force. :wink:
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
