I was the only one in the class who got it right. Thanks for checking my work guys X)

Thanks I'll found out later what the verdict is.

Your first problem is that w=mg not ma.

Homework Statement A 4KG mass is connected by a weightless cord to a 3 kg mass on a smooth surface. The pully rotates about a frictionless axle and has a moment of inertia of 0.5 kgm^2 and radius of 0.3m. Assuming that the cord does not slip on the pully, find a.) the acceleration of the two...

You need to sum your forces before and during the elevator movement. You know what weight is, mg. You know that before the movement there should only be 2 forces and they balance out. Now you need a free body diagram for the movement. You know that the elevator is moving upwards so sum your...

You are probably correct. My book actually does strange things such as G=9.8 instead of G=9.81. I'm pretty used to my answers being slightly off and I'm given full credit along with my classmates.

First find the force the car is exerting. What you want to do is insert that same force into your component of mg. You know the y component of mg by multiplication. So on the diagonal axis you will have a force equal and opposite to the car moving up the same axis, and then you will have mg on...

Okay so you need to think about the force of the car based on the mass and the acceleration. Draw yourself a diagram of an incline of steepness "S". Now put the car on it. You should have the force of the car moving up the incline and mg. You need to find the component of mg that matches the...

B was finding acceleration which was what my attempt was because I found T via the relevant questions.

there are two separate cords

they aren't attached to the same cord

the two equal masses are hanging from the big mass

Hmm I'm wondering why nobody answered me and also a quick comment: I'm not sure if this acceleration would be constant or not..

Homework Statement A uniform, solid cylinder of mass M and radius R rotates on a frictionless horizontal axle. Two equal masses hang from light/weightless cords wrapped around the cylinder. If the system is released from rest, find: A. The tension in each cord. B. The acceleration of each...
