An airplane of mass 3.60 × 105 kg experienced a problem with all its tires when it was about to touch down at a runway of an airport. The tires were deadlocked and not able to roll. The airplane began to skid once it touched down and left behind a 728 m long skid mark on the runway before it came to a stop. Even though everyone on the airplane was safe, the pilot was accused of failing to land the airplane within the allowable speed limit of 80.0 m/s and his pilot license was suspended. Given that the coefficient of kinetic friction between the tires and runway was 0.496.
(i) Determine the work done by friction on the tires.(ii) Use the Work-Energy Theorem to evaluate if the suspension of the pilot’s license should be revoked.

ball is pulled to one side and released to swing as a pendulum, reaching a speed of 5.6 m/s as it passes through the
lowest point. What is the tension in the rope at that point?

The coefficients of friction between the block and the board are μs= 0.450 and μ = 0.400. The end of the board where the block sits is slowly raised until the angle the board makes with the horizontal is α0, and then the block starts to slide down the board.

- Sally wants to hang up some decorations on the side of her house, so she props up a ladder of length L = 3m against a wall at an angle of θ = 50° with respect to the horizontal. The ground is somewhat icy, where the coefficient of static friction between the ground and the ladder’s feet is µ = 0.55; while the wall of her house can be considered frictionless. If Sally has a mass of 60kg and the ladder has a mass of 80kg, what is the max distance that she can climb up the length of the ladder without it slipping? You may assume the ground is perfectly flat, and the wall is perpendicular to the ground.arrow_forwardA ball with a unknown mass is attached to a cable and suspended from the ceiling. The distance from the ceiling to the hanging is 1.9 m (the length of the cable). A person pulls the ball so the cable makes an angle of 64 degrees to the vertical. Determine the maximum speed that can be reached by the mass (in m/s).arrow_forwardA 0.5 kg object moves in a horizontal circular track with a radius of 2.5 m. An external force of 3.0 N, acting always tangent to the track, causes the object to speed up as it goes around. If it starts from rest, its speed at the end of one revolution is:arrow_forward
