Question

A child plays with a toy boat in a pool. When the child pushes the boat down a small distance and releases it, the boat bobs up and down in the water, taking 1.5 seconds to get back to its starting point. If the child pushed the boat down twice as far before releasing it, how long would it take for the boat to return to its starting point?

A) 0.6 s

B) 1.5 s

C) 1.2 s

D) 0.7 s

E) 0.4 s

Answer 1

Toy will execute simple harmonic motion with equillbrium position at top whose time period depends on density of water and not on distance submerged . hence time will remain same

1.5 seconds is correct option
