A student applies an upward force of 56 N to a 5.6-kg physics textbook. Find the book’s acceleration (positive for up, negative for down). answer in miles/seconds squared.

a = F/m = 56 / 5.6 = 10m/s^2,

a=10m/s^2 * (1/1600)mi/m=0.00625mi/s^2

To find the book's acceleration, we can use Newton's second law of motion, which states that the force applied to an object is equal to the mass of the object multiplied by its acceleration. The formula is:

force = mass × acceleration

In this case, the force applied is 56 N, and the mass of the book is 5.6 kg. We need to rearrange the formula to solve for acceleration:

acceleration = force / mass

Plugging in the values, we have:

acceleration = 56 N / 5.6 kg

Dividing 56 N by 5.6 kg gives us the value of acceleration in meters per second squared (m/s^2). However, the question asks for the answer in miles/second squared (mi/s^2). To convert from meters to miles, we need to use the conversion factor: 1 meter = 0.000621371 mile.

So, the acceleration in miles/second squared can be calculated as follows:

acceleration (mi/s^2) = (acceleration (m/s^2)) × (0.000621371 mile/meter)

Now we can calculate the final answer:
