1. Why do you think the use of hallucinogens tends to be illegal? 2. What are the arguments for or against the use of hallucinogens being legal or
illegal? (think of something other than marijuana as well)
3. What about arguments for the other classes of drugs (e. g., depressants,
stimulants)?
4. Specifically for marijuana - doctors have found a way to use marijuana for its health
benefits but removing the hallucinogenic properties. Why are people not satisfried
with this since their main argument for legalization is for its health benefits.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?

Imagine that the rightward current flows in the rod for a short time. as a result, what will the net charge on the right and left ends of the rod become? left end negative and right end positive left end negative and right end negative left end negative and right end nearly neutral left end nearly neutral and right end positive both ends nearly neutral
