Answer in Mechanics | Relativity for Xavier #141519

Author:
March 12th, 2023

Since the force is equal to the ratio of pulse change to time change, then

“F=frac{Delta p}{Delta t}=frac{mtimes Delta v}{Delta t}” ;

Since the period is equal to the ratio of time to the number of oscillations, “T =frac {t} {N} =frac {2} {4} = 0.5” s.

For the half of the period there is a change in speed from 10 to -10 m/s, then

“F=frac{0.05times (10+10)}{0.5times0.5}=4” N.
