Frage 7
Frage
A wooden pallet carrying a load of 600.0 kg rests on a wooden floor and the mu value is 0.280 between the two items. A forklift driver decides to push it without lifting it. What force must be applied to just get the pallet moving?
F = [blank_start]1650[blank_end] N
Antworten
-
1650
Frage 8
Frage
A spring with a natural height of 57 mm is compressed by a 300 g mass to a new height of 51 mm. What is the spring constant for this spring?
The first blank is for the numerical value. The second blank is the units. Put a space between EACH character for the units!
k = [blank_start]750[blank_end] [blank_start]N / m[blank_end]
Antworten
-
750
-
N / m
Frage 9
Frage
What values should be plotted on the x and y axes of a Cartesian graph in order to provide a line whose slope will give you the spring constant?
Antworten
-
x = displacement y = force
-
x = force y = gravity
-
x = distance y = displacement
-
x = distance y = time
Frage 10
Frage
A block is at rest on a slope. What direction does friction act?
Antworten
-
There is no friction is the block is not moving
-
Friction is acting downwards into the slope
-
Friction is acting upwards, parallel to the slope
-
Friction is acting downwards, parallel to the slope
