Question7: Score 0/1 A block of mass 1.2 kg is attached to one end of a spring (with spring constant 8 N/m) whose other end is fixed to a wall. The block sits on a frictionless table. The mass is pulled 0.5 m from it's equilibrium position and released. What is the force acting on the block when it is travelling at it's maximum velocity? Your response Correct response Auto graded Grade: 0/1.0 N/m What is the magnitude of the force acting when the block has a speed of half of it's maximum value? Your response Correct response Auto graded Grade: 0/1.0 @ N. * Total grade: 0.0x1/2 + 0.0x1/2 = 0% + 0% Question8: Score 0/1 A block of mass 0.3 kg is attached to a spring on a frictionless table and set into simple harmonic motion with a period of oscillation of 2 s, and an amplitude of 1 m. A second identical block is dropped onto the first and sticks to it at the point where the block is not moving. What is the maximum speed of the two block system? Your response Correct response 3.141 Auto graded Grade: 0/1.0 @ m * Total grade: 0.0x1/1 = 0%
