Review Part A A 3.0-m -ong ladder, as shown in (Figure 1), leans against a frictionless...
A 3.06m long ladder leans against a frictionless wall. The coefficient of static friction between the ladder and the floor is 0.576. What is the minimum angle that the ladder can make with the floor without slipping?
A uniform ladder of mass m and length l leans at an angle against a frictionless wall. A person of mass M climbs 90% of the way to the top (at 0.9l). Find an expression for the minimum coefficient of static friction needed to keep the ladder from slipping.
A uniform 5-m long ladder weighing 80 N leans against a frictionless vertical wall. The foot of the ladder is 2 m from the wall. What is the minimum coefficient of static friction between the ladder and the floor necessary for the ladder not to slip?
Problems. 1. A uniform ladder of mass m and length / leans at an angle against a frictionless wall. A person of mass M climbs 90% of the way to the top (at 0.91). Find an expression for the minimum coefficient of static friction needed to keep the ladder from slipping. I
A uniform ladder of mass (m = 14.0 kg) and length (L) leans against a frictionless wall, see figure. If the angle θ = 60.0°, find the static friction force between the ladder and the floor when a 60.0-kg person stands two-third of the way up the ladder?
A uniform ladder of mass (m = 15.0 kg) and length (L) leans against a frictionless wall, see figure. If the angle θ = 52.0°, find the static friction force between the ladder and the floor when a 95.0-kg person stands two-third of the way up the ladder?
A uniform ladder of mass m and length l leans at an angle q against a frictionless wall. A person of mass M climbs 90% of the way to the top (at 0.9l). Find an expression for the minimum coefficient of static friction needed to keep the ladder from slipping.
A 5.0-m-long ladder leans against a wall at 4.0 m above a cement floor. The ladder is uniform and has mass m-15.0 kg. Assume the wall is frictionless, but the floor is not. When the ladder is in equilibrium, please find 1. how many forces apply to the ladder? 2. the two conditions for ladder in equilibrium (math expression)? 3. the force Fw that the wall exerts to the ladder 4. the force Fo that the floor exerts to the...
A uniform ladder of length L and mass m leans against a frictionless vertical wall, making an angle of 49° with the horizontal. The coefficient of static friction between the ladder and the ground is 0.45. If your mass is four times that of the ladder, how high can you climb before the ladder begins to slip?
8. A uniform ladder of mass (m = 14.5 kg) and length (L) leans against a frictionless wall, see figure. If the angle θ = 70.0°, find the static friction force between the ladder and the floor when a 80.0-kg person stands half way up the ladder? N
