- 1. A pendulum consists of a small object called a bob hanging from a light cord of fixed length, with the top end of the cord fixed, as shown in the figure. The bob moves from its turning point A, through point B, to the lowest point in its trajectory at C, where it has its maximum speed. Assume the pendulum moves without friction, swinging equally high on both sides. a) Calculate the radial component of the bob's acceleration at Point A. b) Calculate the A c) B tangential component of the bob’s acceleration at point C? Roughly what is the direction of the bob's acceleration at point B? Carrow_forwardTwo bugs, Buzz and Crunchy, are siting on a spinning disk on a horizontal plane. Buzz is sitting halfway and Crunchy is sitting at the outer edge as shown. The radius of the disk is 0.80 m and the disk is rotating with an angular speed of 38 rpm. The coefficient of friction between the bugs and the disk are us = 0.80 and uk= 0.60. What is the magnitude of Buzz's acceleration, in m/s2? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Buzz Crunchyarrow_forwardA board 2.5 m long leans against a vertical wall. It starts to slide down the wall. The instant the bottom end is 2 m from the base of the wall, the top end is moving down the wall at the rate of 2 m/s. At that moment, how fast is the bottom sliding along the horizontal ground. 1.5 m/s 2 m/s 0.5 m/s 2.5 m/sarrow_forward
- A friend is holding a potato gun at a 40 degree angle from the very bottom. It sends out a potato which travels a horizontal distance of 850m. a. How long does it take the potato to hit the ground? b. Your friend has unfortunately not so much as held the potato gun as wedged it in the ground, supporting it vertically but not horizontally. As a result, the bottom end that they hold doesn't move, but the top of the gun moves backward in a circle due to the torque of the recoil. If the potato gun is 2 meters long, and your friend's face is also about 2 meters above the ground, so that it collides with the potato gun once the gun has become vertical, then how quickly is the gun moving when it hits your friend's face?arrow_forward1.a. Two boxes with masses m1=1 kg and m2= 2 kg are connected by a cord running over a pulley. The coefficient of kinetic friction between the first box and the table is 0.20. Neglect the mass of the cord and the pulley, and any friction in the pulley. What is the acceleration of the system? b. What is the velocity obtained by the acceleration found in the previous part?arrow_forwardMost geologists believe that the dinosaurs became extinct 65 million years ago when a large comet or asteroid struck the earth, throwing up so much dust that the sun was blocked out for a period of many months. Suppose an asteroid with a diameter of 2.0 km and a mass of 0.50 × 10¹3 kg hits the earth (6.0 x 1024 kg) with an impact speed of 4.4 x 10 m/s. ▾ Part A What is the earth's recoil speed after such a collision?

- A firecracker moves vertically upward and after reaching the highest point in its vertical trajectory, it starts falling down. After it falls down by 17.7 meters in air it cracks into two identical pieces. One of the pieces shoots off horizontally with 11.8 m/s speed. What would be the magnitude of the velocity of the other piece right after they split? Enter your answer in m/s. On your paper, show both your calculation for the magnitude and also the direction of the velocity vector of the second piece. Show your work in detail including your physics- based reasoning.arrow_forwardA pendulum has a length l (the rope is massless). The mass of the object suspended from the pendulum is m. With rope horizontal θ = 90o When it makes an angle of degrees, we first leave the object at no speed. Any friction can be neglected. Gravitational acceleration g.

At the same time, the vector position of a 5.45 g particle varies as r2 = 3î − 2ît2 − 6ĵt.arrow_forward
- The surface of a pool table is h=0.710 m from the floor. The winner of a competition wants to know if he has broken the world speed record for the break shot of 32 mph (about 14.3 m/s). A. If the winner’s ball landed d=4.95 m from the table’s edge, calculate the speed of his break shot v0. Assume friction is negligible. B. At what speed v1 did his pool ball hit the ground? Image is attached below. Please show all work.arrow_forwardWrecking balls are used to demolish old buildings. A 720 kg steel ball is suspended from a 10-m-long cable on a crane. A hook on the crane slowly pulls the ball back, then releases it. The ball's speed at the lowest point in its arc, just before striking the building, is 4.5 m/s Part A At the lowest point in the ball's arc, O the tension in the cable is less than mg because the ball is moving down. O the tension in the cable is equal to mg because tension and gravity are the only forces and they balance. O the tension in the cable is greater than mg because there has to be a net upward force. Submit Part B What is the tension in the cable when the ball is at its lowest point?
