Answer #1

The answer is 1.2 s

The toy boat is executing simple harmonic oscillations when it is pushed and released. For a simple harmonic oscillation, the time period depends on the mass and the effective restoring force of the medium (water here) and independent of the amplitude of the oscillation. So, irrespective of how far it is pushed, the time period will remain the same as 1.2 s.

    A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
