A person on a swing moves so that the chain is horizontal at the turning points. Show that the centripetal acceleration of the person at the low point of the arc is exactly 2 g, regardless of the length of the chain. This means that the force on the chains at the low point is equal to three times the person's weight.(Hint: The vertical distance between the turning point and the low point equals the length of the chain.)
although the evidence is weak there has been concern in recent years over possible health effects from the magnetic
The aorta is a major artery, rising upward from the left ventricle of the heart and curving down to carry blood to the abdomen and lower half of the body. obtain the magnitude (in m/s2) of the blood's centripetal acceleration
A dielectric-filled parallel-plate capacitor has plate area of 30cm^2 and plate separation of 5mm. The capacitor is connected to a battery that creates a constant voltage of 10V. The dielectric constant is 3. All through the problem, use epsilon_0..
A mountain climber stands at the top of a 52.8m cliff hanging over a calm pool of wat. Find the velocity of the first stone at the instant both stones hit the water
While running, a person dissipates about 0.524 J of mechanical energy per step per kilogram of body mass. If a 65.5 kg person dissipates a power of 76.6 W during a race, explain how fast is the person running?
An attacker at the base of a castle wall 3.63 m high throws a rock straight up with speed 8.80 m/s at a height of 1.51 m above the ground. Find the change in speed of a rock
A ball attached to a string is spinning on a table (ignore any kind of friction), and its angular acceleration is α = 2rad/s. The radius of the trajectory R = 0.4m. Assume that the ball starts from rest, so that ω= 0rad/s at the point θo = 0rad. Find..
