Answer:
Part a)
v = 16.52 m/s
Part b)
v = 7.47 m/s
Explanation:
Part a)
(a) when the large-mass object is the one moving initially
So here we can use momentum conservation as the net force on the system of two masses will be zero
so here we can say
since this is a perfect inelastic collision so after collision both balls will move together with same speed
so here we can say
Part b)
(b) when the small-mass object is the one moving initially
here also we can use momentum conservation as the net force on the system of two masses will be zero
so here we can say
Again this is a perfect inelastic collision so after collision both balls will move together with same speed
so here we can say
Hey!
Formula for calculating work = Force × distance
Work done = Force applied on the object × distance travelled by it.
Hope it helps...!!!
Answer:
Explanation:
As we know that the wavelength of light is given by
now we know that
now from above equation we know
now the diameter of the bead is given as
Now total number of wavelengths that travel in the bead is given as
