Calculate the kinetic energy (KE) of an object which has a massof 5.51 × 102 g, and is traveling in a straightline with a speed of 41.7 m s-1. (Hint: 1 J = 1 kgm2s-2)
Enter only the numerical value below, understood to be in unitsof joules.
2. A 534.8 gram sample of aluminum is initially at25.0 °C. It absorbs 32,600 J of heat from itssurroundings.
What is its final temperature, in °C? (specificheat = for aluminum)
Enter only the numerical value of your calculation in the boxbelow (no units), understood to be in units of °C.Make sure to have the correct number of significant figures anddecimal places in your final answer, otherwise the answer will bemarked as incorrect.
