No idea how to find applied forced based on kinetic friction and acceleration.

AI Thread Summary
To find the applied force on a 10.0 kg box accelerated to 4.00 m/s in 1.00 s with a kinetic friction force of 5.00 N, Newton's second law is applied. The net force can be calculated using the box's acceleration, which is derived from its change in velocity. The applied force must overcome both the frictional force and provide the necessary acceleration. The coefficient of sliding friction can be determined using the formula μ = Ff/Fn, where Fn is the normal force. A clear understanding of the forces and kinematics is essential for solving the problem.

Homework Statement


A 10.0kg box is accelerated from rest to 4.00 m/s in 1.00s. The force of kinetic friction on the box is 5.00N.
A) What is the size of the applied force?

B)What is the coefficient of sliding friction?


Homework Equations


The five kinematic equations?
μ = Ff/Fn
Fn= mg

The Attempt at a Solution


No idea.

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...
