The bob of a pendulum of length I= 0.8 m is released at an angle 0, = 60° with an initial speed of vo=2 m/s. We are interested in the highest point the bob will reach. a) Draw a sketch including the trajectory of the bob and collect the available information, assigning names to all variables. b) Compared to the initial height, you expect the highest point the bob will reach to be [ ] higher [] The answer depends on the direction of the initial velocity of the bob. c) Which principle can you use to calculate the highest point the bob will reach? [] the same height [] lower d) Calculate the highest point the bob will reach. Please use g= 10 m/s² and make sure your units work out. Note: cos(60°) = 0.5 e) Compare your result with your answer to (b) and comment on the agreement.
