- Automatic Zoom 9. Students are given a pendulum. The teacher also provides students with a pictorial model labeled A, 0, and B. Each letter signifies the position of the pendulum. Part A. Which of the following explanations describes the potential and kinetic energy at each position? A. The potential energy is greatest at O and the kinetic energy is equal at A and B. B. The potential energy is greatest at A, followed by B, and then O. C. The kinetic energy is greatest at O, followed by B. and then A D. The potential energy is equal at A and B and the kinetic energy is greatest at O. Part B. What factors could students adjust to explain the transformation between potential and kinetic energy? A. Students could push the pendulum instead of releasing it from position A to increase the kinetic energy at position O. B. Students could move position A higher which would increase the kinetic energy at position O. C. Students could increase the length of the string which would increase the…arrow_forwardAt full swing, a pendulum 8m long, subtends an angle of 34 degrees. How high does the bob of the pendulum rise above its rest position? Use below correct choices as answer and show solution; a.) 55 m b) 45 m c) 35 m d) 25 marrow_forwardBelow is the depicted graph of the velocity of a block that is connected to a spring with an unspecified mass and a force constant of 80 N/m, undergoing oscillation. The time axis is wrongly marked for 1.6 sec. It should be 1.8 sec. Determine the period, frequency, and angular frequency of oscillation? Calculate the maximum displacement of the mass from equilibrium in centimeters? Just so you know: It does not correspond to the amplitude of the velocity graph. What is the peak acceleration of the mass and identify the moments when it transpires?arrow_forward

- A 20kg block starts from rest and slides 6m down an incline as shown below. The block then hits a spring that has a force constant of 200 N/m. The angle of the incline is 30° and there is a coefficient of kinetic friction equal to 0.2 between the block and the incline. HK = 0.2 6m K = 200N/m www 300 Answer the following questions on your own paper and staple it to this sheet. 1. What is the speed of the block as it hits the spring? 2. At what distance from the top does the maximum speed occur? 3. What is the maximum speed of the block? 4. What is the total distance that the spring gets compressed? The spring recoils to push the block back up the incline. 5. What will be the speed of the block when it leaves the spring? 6. How far up the incline will the block travel?
