1. which of the following statements is true (assume there is no friction on the ramp)?
a) the kinetic energy of the skater increases as he rolls up the ramp while the gravitational
potential energy decreases.
b) the gravitational potential energy of the skater decreases as he rolls down the ramp - at the
same time the kinetic energy stays constant since he is always moving.
c) the skater's kinetic energy increases as he rolls down the ramp. the gravitational potential
energy decreases as he rolls down the ramp.
d) the skater's total energy decreases over time and gets converted to thermal energy

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.
