Question

5.4. (a) When a horizontal force equal to its weight is applied to an object on a frictionless surface, what is its acceleration? (b) What is its acceleration when the force is applied vertically upward? 5.5. Compare the tension in the coupling between the first two cars in a train with the tension in the coupling between the last two cars when (a) the train's speed is constant and (b) the train is accelerating.

Step 1

The formula is given by: \[ F = ma \] where F is the force applied and m is the mass of the object. In this case, the force applied is 133 N and the mass is not given. So, we cannot calculate the acceleration without knowing the mass of the object. Show more…
