Hi, I am confused about physics, more specifically force.

I know that the formula for force is:
f=ma

So what if an object traveling at constant speed (acc equals zero) collides with a wall? How would you calculate the force, since there is no acceleration?


There IS force upon the object, as well as acceleration, when collision occurs. Its velocity DOES change during the impact, since it must stop and turn around, stick or bounce off.

In order to calculate the force during impact, you need to know how long the objects are in contact. That depends upon the elastic properties of the surfaces where contact occurs, and whether permanent deformation occurs. This can be difficult to compute accurately. Often an experimental measurement is used

    if no acceleration then mass and acceleration is 0 which means your forces equal eachother and you set them euqal to eachother

    Two stones are thrown simultaneously, one straight upward from the base of a cliff and the other straight downward from the top of the cliff. The height of the cliff is 6.00 m, and the speed with which both stones are thrown is 9.00 m/s. Find the location of the crossing point.
