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. 1) Determine the radius of curvature, Pp, of the path at x = 0.0 m. Your answer must include 2 places after the decimal point and the proper unit. k = 5 kN/m punda Your Answer: Answer y units y = 0.25x². 3 m v X

Please pay attention: the numbers may change from problem to problem since they are randomized. 5) If the block has mass of 35 kg and its initial velocity is 2.7 m/s (at x = 3 m), determine the maximum compression of the spring (after the block has pushed in the spring and come to a stop). The spring constant is given in the image. Your answer must include 3 places after the decimal point and the proper unit. Take g = 9.81 m/s². k = 5 kN/m puudu Your Answer: Answer units y = 0.25x². 3 m v X
Velocity. Suppose the distance travelled by a tanker ship departing from port is given implicitly by the equation 2-4st-75³-0 Where s is the distance in kilometres and it is time in seconds (s). Use implicit differentiation to calculate the velocity of the ship when s= 40 and 14 seconds. Note: Enter your solution as a decimal rounded to four (4) decimal places without units.
