Find the magnitude and direction of the acceleration of the

In summary, acceleration is the rate at which an object's velocity changes over time and is calculated by dividing the change in velocity by the change in time. The magnitude of acceleration can be found by taking the absolute value of the acceleration vector, while the direction is determined by the change in velocity. Acceleration can be negative, indicating a decrease in velocity, or positive, indicating an increase in velocity.

Homework Statement


m=25 kg, F1=88N[E55N],F2=54N[E], mu (coefficient of friction) = 0.350

Homework Equations


FNet=F1+f2-Ff

The Attempt at a Solution


88cos55 + 54=104.47, 88sin55+0=72.1. dheta=tan inverse (72.1/104.47)=34.6 degrees, what direction is Ff is my question and I would appreciate a full solution as well.

you should draw a free body diagram, have you?
there is at least one missing equation, in relevant equations.
i do not believe anyone will completely solve a problem for you here. people will attempt to help you reach your solution.
 

1. What is acceleration?

Acceleration is the rate at which an object's velocity changes over time. It is a vector quantity, meaning it has both magnitude (size) and direction.

2. How is acceleration calculated?

Acceleration is calculated by dividing the change in an object's velocity by the change in time. The formula for acceleration is a = (vf - vi)/t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.

3. How do you find the magnitude of acceleration?

The magnitude of acceleration can be found by taking the absolute value of the acceleration vector. This will give you the numerical value of the acceleration without considering its direction.

4. What is the direction of acceleration?

The direction of acceleration is the same as the direction of the change in velocity. This can be determined by looking at the direction of the initial and final velocities, or by using vector addition to find the direction of the resulting acceleration vector.

5. Can acceleration be negative?

Yes, acceleration can be negative. This indicates that the object is slowing down or changing direction in the opposite direction of its initial velocity. Positive acceleration indicates that the object is speeding up or changing direction in the same direction as its initial velocity.
