Problem 11P
(Note: In Problems, assume a number like 6.4 is accurate to ; and 950 is
unless 950 is said to be “precisely” or “very nearly 950, in which case assume 950
)
What, roughly, is the percent uncertainty in the volume of a spherical beach ball whose radius is r = 2.86 0.09 m?
Soft ball will spend more time to contact and also rebound compare to normal ball because the soft ball having less weight when hits ground it is very lowest force but normal hit the surface force will be more because of this reason the soft ball force is less than the force on the floor compare to normal ball. Here the concept of change in momentum will be exist to clearly understand solution for this problem.change in momentum is equal to mass times the change in velocity. p = mvmv Here we have two object one is soft ball and another one is normal ball.the change momentum of the soft ball will be less because it will take more time to come rest,but normal ball will come fast. p/t = f When t is more the force of the soft ball hit the ground will be less than compare to hard ball when force is less rebound time is more so that force of the soft ball is less than the force of the normal ball.
