Answer:
Explanation:
here it is given that the crate is sliding down with constant speed
so we will have
now we can say
so here we have
a = 0
now from Newton's II law we can say that sum of all forces on the system is always product of mass and its acceleration
so here we will have
Her displacement is 41m. First, she walks 32m to the right, then 12m to the left. I subtract 12 from 32 to get 20m. She walks 28m to the right. Add 28 to 20 and you get 48. Finally, she walks 7m to the left. Subtract 7, then you get 41m.
Answer:
Examples for Rectilinear Motion
1) The use of elevators in public places is an example of rectilinear motion.
2) Gravitational forces acting on objects resulting in free fall is an example of rectilinear motion.
3) Kids sliding down from a slide is a rectilinear motion.
4) The motion of planes in the sky is a rectilinear motion.
