What happens if you jump on a shock absorbent mattress?

kkurt [141]

A shock absorbent mattress is built such that the boxspring of the bed absorbs pressure that is exerted to the bed. Hence, if you jump on the mattress, you would not bounce up and down as much as a normal mattress because the springs do not oscillate much. This is done to endure wear and tear.

Anika asks Eva to roll a basketball and then a bowling ball to her. Which requires more force to roll, and why?

Paul [167]

It's easy to roll the the basket ball than bowling ball

It is because bowling ball is solid spherical ball which will have less moment of inertia

its moment of inertia is given as

$I = \frac{2}{5}mR^2$

While for the hollow ball like basketball we know that moment of inertia is given as

$I' = \frac{2}{3}mR^2$

so here we can see for the same mass if we take basketball then its moment of inertia is more so it is easy to roll basket ball then to roll bowling ball.

So it is easy to roll basket ball then rolling ball
