Question

2) For a ladder of 8 meter long and 60 kg weight, what is the minimum angle it makes with the ground while it leans against a smooth wall. The frictional coefficient of the leg of the ladder on the ground is 0.15. Why the angle is minimum? 3) What is the static stability Factor of a car, which center of gravity of 1.0 meter high, and the tires separation between left and right tires is 2.6 meters. Why is the car rolling to the left while it tries to make right turn? How fast is the velocity can the car make a turn without rolling over to its side? 4) Show the forces on a pendulum. What is the length of a pendulum which has period of 1.6 second. The pendulum has a mass of 30 grams. 5) For a mass and spring system vibrating horizontally, find its frequency of horizontal vibration if the mass is 0.8 kg and spring constant is 400N/m.
