a 60-kilogram high jumper lands on a mat after her jump. the mat brings her to a stop after 1 second. she
was traveling at 5.0 m/sec when she landed on the mat. note: the speed of the jumper at the top of her jump.
before she started to fall toward the mat, was 0 m/sec.
a. what is the change in momentum for the jumper?
b. what is the force felt by the jumper upon impact with the mat?

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.
