Abigail's 8.12 kg bowling ball is traveling at 1.7 m/s and collides with josh's 524 g beach ball that is sitting next to him at the park. the bowling ball leaves the collision with a velocity of 1.44 m/s traveling in the same direction as the beach ball. calculate the speed of the beach ball.

4.03 m/s

Explanation:

The law of conservation of linear momentum dictates that the sum of initial and final momentum should be equal. Momentum is the product of mass and velocity expressed as p=mv.

For this case, the equation would be

Where m represent mass, u and v represent initial and final velocities respectively while subscripts a and j represent Abigail's and Josh's ball respectively

Given info

Mass of Abigail's ball= 8.12 kg

Mass of Josh's ball= 524 g= 0.524 Kg

Initial velocity of Abigail's ball= 1.7 m/s

Initially velocity of Josh's ball= 0 m/s since it is sitting next to Josh to mean its stationery

Final velocity of Abigail's ball= 1.44 m/s

Final velocity of Josh's ball= unknown

Substituting the above given figures into the initial equation then

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
