2) In Figure 2. a 2 kg block is released from the top of a 370 incline at a distance of 0.4 m from a light, unstretched spring. At the end of its slide, the block compresses the spring by 0.1 m. If the coefficiet of kinetic friction between the block and the incline is 0.2. determine the spring constant. 880MM

Trying to convert 1.40mi into kilometers but still havent quite mastered the unit conversion. I tried 1.40mi * (1.609km/1mi) but thats not correct. Please assist me with this

Preliminary Basic Calculations: The speed of sound is fast, but clearly not as great as the speed of light. There is a common observation that you can tell how far away a bolt of lighting is by counting the time in seconds between the flash (which arrives almost instantaneously) and the thunder. Each second of delay means the strike is 1/5 of a mile away. This implies that sound travels about 1/5 mile/sec or (5280/5) ft/sec≈ 1000 ft/sec. THE TIR (A) What is the approximate speed of sound in meters/sec? daca).sdut llod sdt mi is sd dguonit brs trigit (sbunito ngcourts fel bas fal asqo Page 1 of 10

I submitted this before but I don't think the answer was 100% correct. Can someone write it out in full on the answers and how they were achieved?
