A 3.00 kg mass is pushed against a spring and released. If the spring constant of the spring is 7500 N/m and the spring is compressed 10.0 cm:
i. What is the energy stored in the compressed spring? [2 points]
ii. What is the maximum speed ⃗_{0} of the mass? [2 points]
iii. The mass then travels across a rough surface and then up a smooth ramp. The speed
at the beginning of the ramp is ⃗1 = 4.00 m/s. What is the work done by friction as
the mass moves across the rough surface? [2 points]
iv. The block then travels up the smooth ramp and continues on vertically. How high
does it go? [2 points]

Clothing made of several thin layers of fabric with trapped air in between, often called ski clothing, is commonly used in cold climates because it is light, fashionable, and a very effective thermal insulator. so it is no surprise that such clothing has largely replaced thickand heavy old-fashioned coats. (a) consider a jacket made of five layers of 0.1-mm-thick synthetic fabric (k = 0.13 w/m·°c) with 1.5-mm-thick air space (k = 0.026 w/m·°c) between the layers. assuming the inner surface temperature of the jacket to be 28°c and the surface area to be 1.25 m2, determine the rate of heat loss through the jacket when the temperature of the outdoors is 0°c and the heat transfer coefficient at the outer surface is 25 w/m2·°c. (b) what would your response be if the jacket is made of a single layer of 0.5-mm-thick synthetic fabric? what should be the thickness of a wool fabric (k = 0.035 w/m·°c) if the person is to achieve the same level of thermal comfort wearing a thick wool coat instead of a five-layer ski jacket?
