Work = force x distance
200 Newtons x 20 meters
= 4,000 Joules
Explanation:
F net of sled = Tension force by rope - Kinetic friction between ground.
F normal of sled = mg = (67kg)(9.81kg/m^2) = 657.27N.
Kinetic friction = 0.18 (I cannot see the value) * Normal force of sled = 0.18 * 657.27N = 118.31N
So F net of sled = 800N - 118.31N = 681.69N.
(I cannot see what the question is asking for, please check on your own!)
Answer:
Oi, mate its false
Explanation:
because if an leaf floats down from a tree it is not considered an object for a free-fall
We can conclude that it is a longitudinal wave because the wave is traveling through a medium displacing particles<span>
