7. How fast is Michael accelerating if his mass is 10 kg and he is exerting 1,500 Newtons of force?

What is the measurement of how fast an object moves relative to a reference point?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

How does an observation about an object differ from an inference about that object
