Question

The force shown acts on a 2kg object that starts from rest at the origin. Find the speed of the object when it is at the location x = 0.79 m?

Answer 1

To find the speed of the object when it is at the location x = 0.79 m, we need to use the equation for force and motion. Calculate the acceleration using the equation F(x) = ma, and then use the equation v = u + at to find the final speed of the object.

Step-by-step explanation:

To find the speed of the object when it is at the location x = 0.79 m, we need to use the equation for force and motion. The force acting on the object is given by F(x) = (3/√√x) N. We can use this equation to find the acceleration of the object at x = 0.79 m. Once we have the acceleration, we can use the equation v = u + at to find the final speed of the object.

1. Calculate the acceleration, a, at x = 0.79 m using the equation F(x) = ma
2. Use the equation v = u + at to find the final speed of the object, where u is the initial speed (0 since the object starts from rest) and t is the time taken to reach x = 0.79 m

By following these steps, you can calculate the speed of the object when it is at the location x = 0.79 m.
