- I need help with this problem and an explanation for the solution described below (Kinematics):I do appreciate the response to my first question. I understand the approximation of stating that μ = 0.20, just as the object begins to move. But, can you base that approx. on the fact that the object is moving at a constant velocity, as was stated in the explaination above. The problem does not state that the object is moving at a constant velocity. The object is accelerating once the wheels are unlocked---which means the bucket is accelerating. Therefore, we would not be able to say, for the bucket, that T=mgAt t = 9, is the particle speeding up or slowing down? Give a reason for your answer.
- Acceleration of a falling body a. Find the acceleration a(t) = v'(t) of a falling body whose velocity is given in part (a) of Exercise 96. b. Compute lim a(t). Explain your answer as it relates to %3D terminal velocity (Exercise 97).A ball is thrown upwards at an angle of 15.0 deg and an initial speed of 27.5m/s. The experiment is done on earth. What is the vertical component of its acceleration when it reaches the maximum height (in m/s2)? Include the sign to indicate direction.Q1: A dolphin in an aquatic show jumps straight up out of the water at a velocity of 13.0 m/s. (a) List the knowns in this problem. (b) How high does his body rise above the water? To solve this part, first note that the final velocity is now a known and identify its value. Then identify the unknown, and discuss how you chose the appropriate equation to solve for it. After choosing the equation, show your steps in solving for the unknown, checking units, and discuss whether the answer is reasonable. (c) How long is the dolphin in the air? Neglect any effects due to his size or orientation.
