A hockey player strikes a puck, giving it an initial velocity of 15.0 m/s in the positive x-direction. The puck slows uniformly to 6.20 m/s when it has traveled 45.0 m. (Take the direction of initial motion as the positive direction. Indicate the direction with the sign of your answer.) (a) What is the puck's acceleration? (b) At what velocity is it traveling after 2.80 s? (c) How long does it take to travel 45.0 m?

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.
