In anticipation of a long 10 upgrade, a bus driver accelerates at a constant rate of 5 ft/s2 while still on a level section of a highway. Knowing that the speed of the bus was 80 mph as it begins to go upthe hill and that the driver doesnot change the setting on his throttle or shift gears, determine the distance traveled (in miles) by the bus upthe hill when its speed decreased to 50mph. Problem

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

The air that we breath is made mostly of which gaseous molecule

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot
