Select the correct answers. tree branch A monkey is at the end of a 1.5 m swinging 30.0 rope hanging from a tree branch. The branch is 2.0 m above the ground taken as reference 1.5 m level. This can be modeled as the pendulum shown in the image. When the rope makes an 2.0 m angle of 30° with the vertical, the speed at the corresponding position B is Vg is zero. Neglect all nonconservative forces and find h., he and v the speed at the equilibrium position A. ground Select 2 choice(s) Oh, =1.7 m and h, = 1.5 m nh, = 0.50 m and h, = 0.70 m nh, = 1.5 m and h, = 1.7 m O V=0 m/s O KA- 3.9 m/s OVA= 2.0 m/s
The figure below shows a force versus position graph for a spring/block system. If Fs=160N and the block is released at x = 12 cm (not shown on figure) how much work is done on the block by the spring as the block goes from x = + 8.0 cm to x = + 5.0 cm. HInt: Determine k from the graph. Don't forget to convert from cm.

A block attached to a 15 N/m-spring constant spring moves on a frictionless horizontal surface, its position-vs-time graph is shown below. What is the total mechanical energy of the block-spring system, in Joules? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit x (cm) 20 is needed in your answer, it is already given in the question statement. 0 -20- ਲਈ 4 6 8 –t (s)
