O At speeds close to the speed of light, kinetic energy is approximately equal to (1/2)mv. O The energy principle can be written AEsys = Wurr O The definition of work is W - |< F,Ax, FAy, FAz >l. O The definition K=E- mc is valid even for speeds near the speed of light. O The definition of work V = , O The definition of work is W = F,Ax + FAy + FAz. O The energy principle can be written Egys,t- Esys,i + Wsurr (b) An object with mass 120 kg moved in outer space. When it was at location < 8, -30, -2 > its speed was 18 m/s. A single constant force < 190, 490, -210 >N acted on the object while the object moved to location < 11, -35, -5 > m. What is the speed of the object at this final location?

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
