Chapter 6, Problem 6.64AP
A student builds and calibrates an accelerometer and uses it to determine the speed of her car around a certain unbanked highway curve. The accelerometer is a plumb bob with a protractor that she attaches to the roof of her car. A friend riding in the car with the student observes that the plumb bob hangs at an angle of 15.0° from the vertical when the car has a speed of 23.0 m/s. (a) What is the centripetal acceleration of the car rounding the curve? (b) What is the radius of the curve? (c) What is the speed of the car if the plumb bob deflection is 9.00° while rounding the same curve?

I know there is two forces acting on the block, tension force, and gravity, but what exactly is the correct formula? Thank you for your help in figuring this practice problem out.
A tourist looks up at a tall obelisk and desires to determine the height of this object. He estimates that he is 278 meters from the base of the obelisk and the angle from the horizontal is 52.1 degrees. At that moment, a bird drops a twig from the top of the obelisk. How long, in seconds, does it take for the twig to fall to the ground? Assume no initial downward velocity and no drag.
You are working as an expert witness for the defense of a container ship captain whose ship ran into a reef surrounding a Caribbean island. The captain is being charged with intentionally running the ship into the reef. In discovery, the following information has been presented, and attorneys on both sides have stipulated that the information is correct: The ship was traveling at 2.50 m/s toward the reef when a mechanical failure caused the rudder to jam in the straight-ahead position. At that point in time, the ship was 900 m from the reef. The wind was blowing directly toward the reef, and exerting a constant force of 9.00 x 103 N on the boat in a direction toward the reef. The mass of the ship and its cargo was 5.50 x 107 kg. During the preparation for the trial, the captain claims that without control of the direction of travel, the only choice he had was to put the engines in reverse at maximum power, such that the total force exerted by the frictional drag force of the water and…

- In deep space, an astronaut is whipping a heavy tool around in a circle by a taut cable. The cable is 1 meter long (from the astronaut's fist to the tool), and the tool makes a full trip around the circle in half a second as it moves with constant speed. The mass of the tool is 10 kg. What is the tension in the cable?arrow_forward*59. A block is hung by a string from the inside roof of a van. When the van goes straight ahead at a speed of 28 m/s, the block hangs vertically down. But when the van maintains this same speed around an unbanked curve (radius = 150 m), the block swings toward the outside of the curve. Then the string makes an angle 0 with the vertical. Find 0.arrow_forwardOn the International Space Station an object with mass m = 290 g is attached to a massless string L = 0.99 m. The string can handle a tension of T = 6.8 N before breaking.

Give your answer in units of m/s.arrow_forward
- A small object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. The upper end of the rope is attached to the ceiling.

As the object swings through its lowest position, where the rope is vertical, the speed of the object is 3.30 m/s. At this point in the motion, what is the tension in the rope? (Use g=9.80m/s2.)arrow_forwardA 3500 kg flatbed truck is carrying an unsecured 400 kg box of wine glasses. The coefficient of static friction between the box and the truck bed is Usb=0.50, the coefficient of rolling friction between the truck's tires and the road is Urt=0.03. The truck comes to an unbanked curve in the road having a 40m radius. What is the maximum speed with which the truck can take the curve without damaging the wine glasses? Note that in order for the wine glasses to not be damaged, the box they're in should not slide on the truck bed and the truck itself should not slide on the road while taking the curve.arrow_forward

- A small object of mass 0.500 kg is attached by a 0.840 m-long cord to a pin set into the surface of a frictionless table top. The object moves in a circle on the horizontal surface with a speed of 8.80 m/s. What is the tension in the cord?arrow_forwardA 0.32 kg ball is attached to a 1.4 m long string, and moves in a circular path on a smooth horizontal table. If the ball takes 0.6 seconds for each complete revolution, what is the tension in the string in N?arrow_forwardThe physics of circular motion sets an upper limit to the speed of human walking. (If you need to go faster, your gait changes from a walk to a run.) If you take a few steps and watch what's happening, you'll see that your body pivots in circular motion over your forward foot as you bring your rear foot forward for the next step. As you do so, the normal force of the ground on your foot decreases and your body tries to "lift off" from the ground. A. A person's center of mass is very near the hips, at the top of the legs. Model a person as a particle of mass m at the top of a leg of length L. Find an expression for the person's maximum walking speed vmax Express your answer in terms of the variables L and appropriate constants. b.)Evaluate your expression for the maximum walking speed of a 70 kg person with a typical leg length of 70 cm . Give your answer in m/s. c.) Give your answer in mph.arrow_forward
