Textbook Question
Chapter 14, Problem 30P
A building is being knocked down with a wrecking ball, which is a big metal sphere that swings on a 10-m-long cable. You are (unwisely!) standing directly beneath the point from which the wrecking ball is hung when you notice that the ball has just been released and is swinging directly toward you. How much time do you have to move out of the way?

- A physics lab instructor is working on a new demonstration. She attaches two identical copper balls with mass m = 0.180 g to threads of length L as shown in the figure. There are two strings in the figure. The top of each string is connected to the ceiling, and both strings are connected at the same point. The bottom of each string is connected to a spherical mass labeled m. Both strings have length L and hang at an angle of ? to the vertical, with the two strings on opposite sides of the vertical. Both balls have the same charge of 7.60 nC, and are in static equilibrium when ? = 4.75°. What is L (in m)? Assume the threads are massless. m (b) What If? The charge on both balls is increased until each thread makes an angle of ? = 9.50° with the vertical. If both balls have the same electric charge, what is the charge (in nC) on each ball in this case?arrow_forwardNative people throughout North and South America used a bola to hunt for birds and animals. A bola can consist of three stones, each with mass m, at the ends of three light cords, each with length ℓ. The other ends of the cords are tied together to form a Y. The hunter holds one stone and swings the other two above his head as shown. Both these stones move together in a horizontal circle of radius 2ℓ with speed υ0. At a moment when the horizontal component of their velocity is directed toward the quarry, the hunter releases the stone in his hand. As the bola flies through the air, the cords quickly take a stable arrangement with constant 120-degree angles between them as shown. In the vertical direction, the bola is in free fall. Gravitational forces exerted by the Earth make the junction of the cords move with the downward acceleration g→. You may ignore the vertical motion as you proceed to describe the horizontal motion of the bola. In terms of m, ℓ, and υ0, calculate (a) the…arrow_forwardA long limp spring is hung from a beam; the spring's bottom is 660 mm above the table.

What is the cylinder's velocity, half-way to the bottom turn-around?arrow_forward
- A construction worker pulls a five-meter plank up the side of a building under construction by means of a rope tied to one end of the plank (see figure). Assume the opposite end of the plank follows a path perpendicular to the wall of the building and the worker pulls the rope at a rate of 0.14 meter per second. How fast is the end of the plank sliding along the ground when it is 1.8 meters from the wall of the building? (Round your answer to two decimal places.) 5 m m/sec Need Help?
