I thought it would be possible because of that double bond.

Homework Statement Ive narrowed the question down into A,B,C as the possible answers, but I can't determine if it is E,Z or neither configured. Any help would be great.

Thanks for the help, I understand the first step and where the bromine's attach to. What exactly is happening in the second step with the methoxide ions?

Well The H would attack the double bonds and form the most stable carbo-cation?

Homework Statement The Attempt at a Solution I'm confused on what is happening in this reaction, and where carbo-cations are being formed. Any help would be great. Thanks.

So would I be using static coefficient of friction? Would the kinetic coefficient of friction come into play?

Homework Statement A constant speed conveyor belt delivers stones and drops them in a bin as shown. The conveyor ends with a pulley with a 100 mm radius. The coefficients of friction on the belt are μs = 0.20 and μk = 0. If the velocity of the pulley is 0.1 m/s, what is the angle,theta...

You need to take relative acceleration into account I am pretty sure.

I understand that I need to use Newton's 2nd law, but I am confused on the swinging of the pendulum. Plus it looks like I would need to take relative accelerations into account. Since the swinging of the sphere is moving with the block.

I don't think work and energy can be used here since you are looking for the accelerations. Would relative acceleration need to be considered for this problem since the acceleration of the sphere is moving while the block is moving.

I have another question then. Since the problem is asking "the instant it is released from rest" can you assume the velocity is 0 at that instant? Therefore the component of normal acceleration is 0?

That's true, I have another question then. Since the problem is asking "the instant it is released from rest" can you assume the velocity is 0 at that instant? Therefore the component of normal acceleration is 0?

Mechanics:Dynamics (Newton's 2nd Law?) Homework Statement A sphere S with a mass of 5 kg is attached by a rigid rod to 1 kg block B which is free to slide with no friction in a horizontal slot. The system is released from rest. At the instant when it is released, find the tension in the...

Sorry wrong section

Homework Statement A sphere S with a mass of 5 kg is attached by a rigid rod to 1 kg block B which is free to slide with no friction in a horizontal slot. The system is released from rest. At the instant when it is released, find the tension in the rod and the accelerations of both blocks...
