AI Thread Summary
To solve the incline problem involving a 250 g cart with a propeller force of 0.3 N moving down a 30-degree incline with an acceleration of 3.5 m/s², it's essential to apply Newton's second law and analyze the forces acting on the cart. The force of friction can be calculated by considering the net force acting on the cart, which includes gravitational force, propeller force, and friction. The coefficient of friction can then be determined using the frictional force and the normal force. Drawing a free body diagram is recommended to visualize the forces and clarify the calculations. Understanding these concepts is crucial for success in exams rather than seeking shortcuts.

can anyone show exactly how to solve this problem with equations and all?


a cart on wheels with a mass of 250 g has a motor driven propeller with a force P of .3 N, and it moved down an incline of 30 degrees with an acceleration of 3.5 m/s^2.

What is the force of friction ?

determine coefficent of friction?


Thanks!

No, because it wouldn't help you. From your other post, I know your knowledge is very sketchy, and if you continue to look for shortcuts, you will come short in the exam.
 
When you have no clue what to do, draw a free body diagram
 
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...
