A 250N effort force is exerted on an ideal machine with an actual mechanical advantage of 4. If the effort distance is 3 meters, calculate the resistance distance. (Hint: You'll have trouble solving this in one step. But think about what measurement you could solve for in one step, and if that measurement would help answer the question.) I​

1/0.14nm = 10^10/1.4 a lot

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
