Answer:
that is preatty balenced m8
Explanation:
newton 1st law: w no external force, a body will stay at rest or in constant uniform motion.
a motor raises the car up the tower. cuz it moves w/ constant vel, there is no external force: the motor force is the same n in opposity direction as the gravity force on car.
Earth's inner core is solid even though the temperature is so high because the pressure is also very high.
Hope this helped:)
Answer:
2. A force of 50 N is applied to the object for a distance of 2.0 m. Assume that object（the mass of the object is 3kg）
was at rest at the beginning, what speed did it achieved because of the work done on it? (Hint:
Calculate the works performed by the force first.)
I figured that is 8.2m/S，I am just not sure can anyone help me i much appreciate it.
It is is real because potential energy is stored inside gravitational energy.
