One-dimensional impulse force

In summary, the problem involves a 3.0-kg object being acted upon by a one-dimensional impulse force, as shown in the given graph. The task is to find the magnitude of the impulse given to the object, the magnitude of the average force, and the final speed of the object if it had an initial speed of 6.0 m/s. The equation F = (Po-P)/(To-T) can be used to solve for these values, but the given information is not sufficient and further clarification from the instructor may be needed.

The Attempt at a Solution



I have need some help here what my instructor has us read gives no help in solving 99% of our problems.


Thanks

For a graph of y vs x, if you find the area under that graph, you get what the product xy represents.

ok so would (b) be
(f+fo)/2
(900+0)/2
450N
 

1. What is the definition of one-dimensional impulse force?

One-dimensional impulse force is a sudden, strong, and short-lived force applied in a single direction on an object. It is characterized by its magnitude, direction, and duration.

2. How is one-dimensional impulse force different from one-dimensional constant force?

One-dimensional impulse force is a short-lived force that is applied only once, while one-dimensional constant force is applied continuously over a specific period. Impulse force can cause a change in an object's momentum, while constant force can cause a change in an object's velocity.

3. How is one-dimensional impulse force measured?

One-dimensional impulse force is measured in Newton-seconds (Ns) or kilogram-meters per second (kg∙m/s). Both units represent the product of force and duration of the force.

4. What is the significance of one-dimensional impulse force in physics?

One-dimensional impulse force is significant in physics because it allows us to understand the changes in an object's momentum and velocity due to sudden impacts or collisions. It is also used in the study of motion and helps us analyze and predict the behavior of objects in motion.

5. How do you calculate the one-dimensional impulse force?

The formula for calculating one-dimensional impulse force is F∆t = ∆p, where F is the force applied, ∆t is the duration of the force, and ∆p is the change in momentum of the object. This can also be written as F = ∆p/∆t.
