3. For this series of 5 questions, a block is released from the position shown with a certain initial velocity. It then slides down the smooth (friction-less) path for which the function is given in the image. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 2) As the block slides down, its potential energy converts into kinetic energy. If its initial velocity is 1.5 m/s (at x = 3 m), determine its velocity, v, at x = 3.0 m. Your answer must include 2 places after the decimal point and the proper unit. Take g = 9.81 m/s².

I am trying to practice this problem using a checker online, but everytime I recalculate my answer it always says it's incorrect. So far I have calculated and tried to input the following values: 1 hp, 1.01 hp, 0.8 hp, and 12.53 hp, but it always keeps saying they are incorrect. Please help show me the correct steps on how to get the correct answer as I am trying to learn this process. Thank you!
Learning Goal: To be able to add and subtract vectors using geometric and vector addition. A brother and sister are playing in the woods, when suddenly the brother realizes that they are separated. The last place he remembers seeing his sister is at a particularly large tree. The brother traveled d₁ = 21.0 m at 0₁ = 26.0° from the tree then turned and traveled 4 = d2 11.0 m at 02 = 140°. Meanwhile, the sister traveled d3 = 17.5 m at an angle of 03-117° from the tree. The angles are given with respect to east with counterclockwise being defined as positive(Figure 1) Figure d3 03 d₂ 0₁ 0₂ d₁ 1 of 4 X > v Confect Part C Distance to home - After the boy has found his sister, they want to travel the shortest path home.

1. For this series of 4 questions, a rider rides in a car that is connected to a 4-m rod, and rotates about the z axis. The rod of negligible mass is subjected to a constant couple moment of M, and the engine of the car supplies a traction force of F. Neglect the size of the car. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 2) If the total mass of the car and the rider is 125 kg, at the car moves at a velocity of 7.5 m/s, what is the magnitude of the angular momentum of the car-rider system in kg•m2/s about the z axis? Your answer must include 1 place after the decimal point. 4 m M Your Answer: Answer

2. For this series of 4 questions, a man sits in the chair which is pin-connected to the 10-m frame BC. Frame BC rotates counterclockwise. Your final goal is to determine the magnitude of the support force N exerted by the chair on the man at the instant 0 = 30°. But before that, you need to answer some other questions. Please pay attention: the numbers may change from problem to problem since they are randomized. 3) If the two unknowns, N and N₁, represents the tangential component and normal component of the support force N respectively, and the man has mass of m, select the correct equations of motion that, when used together, can solve for the support force N exerted by the chair on the man at the instant = 30°.

25. A student wants to perform an experiment where they have to measure the time interval for a ball bearing rolling down a slope (as with your first practical), in order to determine the acceleration on the ball-bearing. They take 1 measurement for every distance (they move the end of the measuring equipment 10 cm further way every time), and then they plot a graph. This graph comes out with very scattered values that do not form a straight line at all. What could be the reason for this? Choose all correct answers. A. They should have taken more than one measurement at every distance. B. The stopping wires might have malfunctioned sometimes, so they should have made sure that the stopping wires only touched the metal when the ball bearing rolled over it. C. The graph is fine with only one value measured per distance. It is the acceleration that was not consistent. Nothing needs to be changed. D. The graph axes need to be adjusted to make the data show a straight line.
Hello. Answer is s=5.76m (how far the car travels when the driver slams brake on an inclined surface). I am uploading this question as the example answer's working out was so horrific I cannot follow through. I would like to see working out how the calculations equate to the answer being s=5.76m. Many thanks
