A scientist is using a calorimeter to determine the specific heat of an
unknow substance. The sample lost 2457 J of energy to the water bath as
it cooled from 95.8*C to 29.6*C. If the sample has a mass of 95.2g, what is
the substances specific heat?

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
