4. Three people are pushing a 500 kg of box in the same direction. Applied forces are 30 N, 20 N, and 10 N respectively. If the acceleration of the box is 0.02 m/s2, what is the magnitude of a force created by friction?

Respuesta :

Chelboy

Answer:50N

Explanation:

mass=500kg

Total force=30+20+10=60N

Acceleration=0.02m/s^2

Resultant force=mass x acceleration

Resultant force=500 x 0.02

Resultant force=10N

Frictional force=total force - resultant force

Frictional force=60-10=50N
