Answer:
Explanation:
The work required to push will be equal to work done by friction . Let d be the displacement required .
force of friction = mg x μ where m is mass of the suitcase , μ be the coefficient of friction
work done by force of friction
mg x μ x d = 660
80 x 9.8 x .272 x d = 660
d = 3 .1 m .
Answer:
friction help to slow motion in other word it oppose motion, but in a frictionless environment object would move with difficult stopping point.
Answer it will move slower:
Explanation: cause the force that’s opposite of it
Correct me if I’m wrong but I think it’s A
Explanation:
Runner A has already reached about 50m in around 5s.
The type of friction of a kite suspended
in the sky that is flowing back and forth is fluid friction. The fluid here is
the air that helps the kite move back and forth. The kite feels a drag force
due to air which acts in the upward direction.
