I (formula or tips) for solving friction force question

AI Thread Summary
To determine the maximum force of static friction exerted on the 35kg crate, multiply the weight of the crate by the coefficient of static friction (0.175), resulting in a maximum static friction force of approximately 60.75 N. The maximum acceleration that static friction can cause the crate is found by dividing this friction force by the crate's mass, yielding an acceleration of about 1.73 m/s². Understanding that static friction provides the necessary force to prevent sliding is crucial for solving the problem. The relationship between the truck's acceleration and the friction force is key to finding the solution. This approach effectively addresses the questions posed regarding static friction and acceleration.

the question is

A 35kg crate rests on the back end of a flat bed truck. the coefficient of static friction between the crate and the bed is 0.175

what is the maximum force of static friction that the truck's bed can exert on the crate?

b) what is the maximum acceleration the static friction can cause the crate to have?

please help..
thakn you :smile:

What is the force on the crate when the truck's acceleration is a? (with the box not sliding) What supplies that force? (hint: it has something to do with friction). What is the maximum force of (static) friction between the truck and the box? Answer those questions and you will be able to solve this.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
