Answer:
They will come back at the same time.
Explanation:
The angular velocity equation of ω where ω is the frequency of the movement, dependent on the angle. But since swings are simple pendulums and their angles of 8 and 4 degrees are small, they will come back to their starting points at the same time.
I hope this answer helps.
Answer:
Explanation:
Given
mass of sled =26 kg
coefficient of static friction
coefficient of kinetic friction
In order to move sled from rest we need to provide a force greater than static friction which is given by
After Moving Sled kinetic friction comes in to play which is less than static friction
therefore minimum force to keep moving sledge at constant velocity is 18.34 N
