What is wanted friction?
This presumably refers to friction which we find useful. For instance, if you stand on a ladder which is leaning against a wall, it is friction which stops the ladder from slipping. When you walk, friction between your shoes and the ground enables you to push yourself forwards. If the friction is not big enough, you just slip, as on ice.
What will be the reaction if the action is you leaning on a wall?
The reaction is the wall pushing back on you.
Why is a ladder considered an inclined plane?
A ladder can be considered an inclined plane because it forms a sloping surface that allows for easier vertical movement. By leaning the ladder against a wall or structure, it creates an angle which reduces the effort required to climb compared to climbing straight up. Just like an inclined plane, a ladder allows someone to use less force to overcome the vertical height.
An 80kg man is 14 of a way up a 10m ladder that is resting against a smooth frictionless wall What is the friction force if the ladder weighs 20kg and makes an angle of 60 degrees?
170 newtons
Why can you not raise legs of one side when our other leg and hand is pressed against wall?
because you will lose your balance I THINK THAT ITS IN EQUILIBRIUM POSITION...... OR because we are applying the force towards wall from body.
A 15-foot ladder is leaning against a 30-foot wall The bottom end of the ladder is 9 feet from the wall How many feet above the ground does the ladder touch the wall?
12
A 5 foot ladder is leaning against a 4 foot wall How many feet above the ground does the ladder touch the wall?
9
A ladder is leaning against a wall If the angle is between the ground and the ladder at 60 degrees and the wall is 4m how long is the ladder Give exact values?
If the angle between the ladder and the ground is 60 deg, and you know the angle between the ground and the wall is 90 deg, then you have a 30-60-90 degree triangle, which is a common triangle. You should memorize this one. The commonest sides of this right triangle are 4-5-6, with the longest side being the hypoteneuse, in this case the ladder leaning from the ground to the wall. The wall is 4m high, the base of the ladder would be 5m out from the wall, and the length of the ladder is 6m.
A 10 foot ladder is leaning against a vertical wall the base of the ladder is 3 feet from the wall how high is the point where the ladder touches the wall?
13
A 5 foot ladder is leaning against a 4 foot wall how far must the bottom of the ladder be from the base of the wall so that the top of the ladder rests on the top of the wall?
1 i think other people feel free to change this
A ladder is leaning against a wall if you were going to climb the ladder are you better off if there is no friction between the ladder and the wall or ladder and the floor?
No. if the floor is smooth you must have friction between the ladder and the floor, or the ladder would just slide away. Technically you could do without friction between wall and ladder, but even that can be helpful in preventing the ladder from going sideways.
What are Real life examples of slope?
A ladder leaning against a wall. The slated part of the roof of a house.
Ten points for how leadership expressed?
Can give you one. Leadership is leaning the ladder against the right wall, where management ensures the ladder is properly set up.
A 48-foot ladder is leaning against the wall of a building The top of the ladder is touching the ledge of a window that is 45 feet off the ground About how far is the base of the ladder from the wal?
93
A 15 foot ladder is leaning against a 30 foot wallthe bottom end of the ladder is 9 feet from the wallhow many feet above the ground does the ladder touch the wall?
12 feet.
A ladder 10 ft long leaning against a wall at a 71 angle how high up the wall does the ladder reach?
10 sin71 = 10 x 0.9455 = 9.455 feet (just under 9' 5½")
What is the height of ladder which is leaning at 60 degree from the wall and separated with a distance of 4.2cm from the wall?
cos60=4.2cm/x x=4.2cm/cos60 x=8.4cm Therefore the height of the ladder is 8.4cm. However, i think you mean meters because that is a very tiny ladder lol.
