in a spring-mass system, the spring constant is 50 −1 and the block of mass 1 kg is displaced by 0.01 m to the right before being released, calculate the (a) restoring force at t = 0, (b) restoring force when the block travels to the other extreme, and (c) The restoring force in the static equilibrium position.

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask
