Answer:
10.125 meters?
Explanation:
Im taking 5.75m/s + 1.25 m/s/s (3.5) = my answer.
In those 3.5 seconds it travels 4.375.
I added that to 5.75 to get 10.125m
Along plate edges, at points where oceanic or continental plates meet ot at the edges of the plates
Answer:
W = 0J
Explanation:
The work done by the dresser is described as
W = f d (cos θ)
F has been given as the weight of this dresser. And it is 3500 N
d = 0 m
When you put these values into the equation
W = 3500 x 0 x cosθ
W = 0 J
This value tells us that the work done on this dresser is zero. No work has been done. Therefore the last option answers the question.
Answer:
0.20
Explanation:
The box is moving at constant velocity, which means that its acceleration is zero; so, the net force acting on the box is zero as well.
There are two forces acting in the horizontal direction:
- The pushing force: F = 99 N, forward
- The frictional force:
, backward, with
coefficient of kinetic friction
m = 50 kg mass of the box
g = 9.8 m/s^2 gravitational acceleration
The net force must be zero, so we have

which we can solve to find the coefficient of kinetic friction:
