VR of a single movable Pulley is 2,why?
1 answer:
Explanation:
Hey, there!!
Single movable pulley has 2 VR because in single fixed pulley, load is supported with two segments of the string. It makes the effort distance double of the load distance. {As VR = No.of pulley used or number of rope segments that supports the load.}

Explanation:
because it doesn't depend upon other unit like kg meter and second
Step 1: list known info distance(change in position (Δx))= 18m+22m= 40m time= 20 seconds Step 2 :solve for velocity velocity= Δx÷time v= 40/20= 2m/sAnswer: the velocity is 2 meters per a second (m/s)
Answer:
43.68 J
Explanation:
Distance moved= 7.8 m
Force = 5.6 N
Work Done= Distance moved * Force
= 7.8 *5.6
=43.68 Joules
Answer:
its not moving at a constant velocity because it is slowing down
Explanation:
Answer:
Explanation:
Potential energy is minus the integral of Fdx. Doing the integration yields:
so
Now for x=3.0m
