Review. The mass of a car is 1 500 kg. The shape of the cars body is such that its aerodynamic drag coefficient is D = 0.330 and its frontal area is 2.50 m2. Assuming the drag force is proportional to 2 and ignoring other sources of friction, calculate the power required to maintain a speed of 100 km/h as the car climbs a long hill sloping at 3.20.
Review. Why is the following situation impossible? An athlete tests her hand strength by having an assistant hang weights from her belt as she hangs onto a horizontal bar with her hands. When the weights hanging on her belt have increased to 80% of her body weight, her hands can no longer support her and she drops to the floor. Frustrated at not meeting her hand-strength goal, she decides to swing on a trapeze. The trapeze consists of a bar suspended by two parallel ropes, each of length , allowing performers to swing in a vertical circular are (Fig. P8.38). The athlete holds the bar and steps off an elevated platform, starting from rest with the ropes at an angle i = 60.0 with respect to the vertical. As she swings several times back and forth in a circular are, she forgets her frustration related to the hand-strength test. Assume the size of the performers body is small compared to the length and air resistance is negligible. Figure P8.38
A huge pendulum consists of a 200-kg ball at the end of a cable 15 m long. If the pendulum is drawn back to an angle of 37 degrees and released, what maximum force must the cable withstand as the pendulum swings back and forth?
An ornament of mass 40.6 g is attached to a vertical ideal spring with a force constant (spring constant) of 45.6 N/m. The ornament is then lowered very slowly until the spring stops stretching. How much does the spring stretch?

A very light and flexible rope is 40 cm long and is at one end attached to the ceiling. When we hang a 100 gram weight on its other end, the rope is extended by 6.0 cm. The weight is then pulled vertically down so that the ropes length is 80 cm, and then we let go of it. How fast does the weight fly into the ceiling?
