What is the net force what is the magnitude and direction of the net force on a car that has a force of 925N East and 358N West applied to it? a ball if a force of 4.65N is applied East and a force of 8.46N is allied South? please upload answer here thank you

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)

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
