Q22. An object is shot straight up from 7 m above ground level, and returns to the ground after 2.3 s. If the effects of the air are neglected, what is the highest position it has reached (as measured from the ground)? Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper SI unit. Take g = 9.81 m/s². Your Answer: Answer units

You have the six pieces of metal listed below plus a beaker of water containing 400. g of water. The water temperature is 21.0 °C. Metals Specific Heat (J/g. K) Mass (g) 1. Al 0.9002 100. 2. Al 3. Au 4. Au 5. Zn 6. Zn 0.9002 0.1289 0.1289 0.3860 0.3860 50. 100. 50. 100. 50. The specific heat capacity of water is 4.184 J/g °C.
