Atennis ball was thrown into the air with a speed of 22.5 m/s. it was caught at the same height above the ground. a. how fast was the ball moving at the peak of its path? b. what was the acceleration on the ball as the ball was moving upward? c. what was the acceleration on the ball as the ball was moving downward? d. what was the acceleration on the ball at the peak of its path? e. how much time was the ball in the air? f. how fast was the ball moving when it was caught?

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
