A 50-N crate is pulled up a 5-m inclined plane by a worker at constant velocity. If the plane is inclined at an angle of 37° to

the horizontal and there exists a constant frictional force of 10 N between the crate and the surface, what is the force applied by the worker?

Answer:F=40.09 N

Explanation:

Given

weight of crate W=50 N

Inclination \theta =37^{\circ}

Frictional Force f=10 N

as the crate is moving with constant velocity therefore net Force on crate is zero

F-50\sin (37)-f=0

F=50\sin (37)+10

F=30.09+10

F=40.09 N

You throw a rock horizontally out of a 7th story window. You time that it takes 3.7 seconds to hit the ground, and measure that
Nady [450]
Since we are only looking at the vertical height, we can use the free fall equation to find the height:
h = 0.5*g*t^2, where h is height in m, g is acceleration due to gravity (9.81 m/s^2), and t is time in seconds
h = 0.5*(9.81 m/s^2)*(3.7 s)^2
h = 67.15 m
Therefore, the 7th floor window is 67.15 m above ground level.
