Answer:
When you know both the speed and direction of an object's motion, you know the velocity of the object.
1500 kg is the mass of a truck if it produces a force of 9,000 N while accelerating at a rate of 6 m/s²
F=ma
m=F/a
m= 9,000 N / 6 m/s²
m=1500 kg
In physics, mass is used to convey inertia, a property common to all matter. In essence, it is the resistance of a mass of matter to altering its course or speed in response to the application of a force. The more mass a body has, the less of a change an applied force makes. Using Planck's constant, the kilogram, the ISU's unit of mass, is equivalent to 6.62607015 1034 joule seconds (SI). One kilogram is multiplied by one square meter per second to yield one joule. Since the second and the meter have already been defined in terms of other physical constants, the kilogram is determined by precise measurements of Planck's constant.
