Think It Over (Page 116)

Question 1.

What will be the magnitude of velocity of the child at the bottom of the blue slide? Class 9

Answer:

The velocity at the bottom depends on the height of the slide and is given by v = [latex]\sqrt{2 g h}[/latex], where h is the height of the slide.

Question 2.

Will two children of different masses reach the bottom of the same slide with the same velocity? Class 9

Answer:

Yes, both will reach with the same velocity because the velocity depends on height and gravity, not on mass.

Question 3.

Which of the slides will result in the largest magnitude of velocity for the child at its bottom? Class 9

Answer:

The slide with the greatest height will result in the largest velocity at the bottom, regardless of its shape.
