To save energy and money, Jackie Smith replaced the 122 Watt incandescent light bulb in her house with a 18 Watt CFL bulb. The expected life of incandescent and CFL bulbs is 1,000 and 10,000 hours respectively. The purchase price of an incandescent bulb is $0.51 and for the CFL it is $5.88. The cost of electricity is 0.06 $ per kWh. What is her total savings over the lifetime of the CFL

Amass m = 74 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius r = 18.4 m and finally a flat straight section at the same height as the center of the loop (18.4 m off the ground). since the mass would not make it around the loop if released from the height of the top of the loop (do you know why? ) it must be released above the top of the loop-the-loop height. (assume the mass never leaves the smooth track at any point on its path.) 1. what is the minimum speed the block must have at the top of the loop to make it around the loop-the-loop without leaving the track? 2. what height above the ground must the mass begin to make it around the loop-the-loop? 3. if the mass has just enough speed to make it around the loop without leaving the track, what will its speed be at the bottom of the loop? 4. if the mass has just enough speed to make it around the loop without leaving the track, what is its speed at the final flat level (18.4 m off the ground)? 5. now a spring with spring constant k = 15600 n/m is used on the final flat surface to stop the mass. how far does the spring compress?
