A car is waiting at an intersection. The traffic light turns green, and with some delay the driver steps on the accelerator pedal. The acceleration of the car as a function of time is shown in the figure.
What is the final velocity of the car once it is done
accelerating?

A variety of spectra for an organic compound with molecular
formula C10H16O are presented below. The
experimental accurate mass using (+) APCI source is 153.1280 u. The
1H, 13C, COSY, HSQC and HMBC NMR spectra are given in the following
slides. Propose a structure for this unknown and answer or address
the following questions or requirements:
d. If there are still any questionable assignments, propose
additional NMR experiments which would solve those questions and
briefly explain specifically what correlations you...

A car is waiting at an intersection. When the traffic light
turns green, the car starts moving. After some time the car comes
to rest at another traffic light. The figure below shows the
velocity of the car as a function of time.What is the acceleration of the car in the first stage?What is the acceleration of the car in the third stage?What is the total distance travelled by the car between the two
traffic lights?
At the instant the traffic light turns green, a car that has been waiting at an intersection starts ahead with a constant acceleration of 3.2 m/s^2. At the same instant a truck, traveling with a constant speed of 20 m/s overtakes and passes the car. (a) How far beyond its starting point does the car overtake the truck? (b) How fast is the car traveling when it overtakes the truck?
Assign the NMR peaks below DIRECTLY onto the paper,
please!!!!
The impurities are water at 2.19 ppm and acetone at 1.6 ppm. So
just ignore those peaks. The peaks for the aromatic Hydrogens can
be grouped up to one (I believe they are the left most peaks at
around 7 to 7.5 ppm. Given that please assign the rest of the
hydrogens.
