A motorcycle with a mass of 875 kg is moving with an eastward velocity of 70 m/s and collides with another motorcycle with the same mass. The two motorcycles get tangles together in the collision and afterwards their combined mass had a velocity of 40 m/s west. what is the initial velocity of the second motorcycle? (include direction) PLEASE HELP I'M ON TIME LIMIT

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
