If the elevator’s mass is 1,000 kg, and the counter weight’s mass is 850kg, what would be the system’s acceleration

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?

The energy produced as a result of this flow of electrons from atom to atom is called
