Question

Final velocities And loss in K.E an Inelastic head-on collision:?​

Answer 1

Answer:

1. a collision in which the object stick together called perfectly inelastic. inelastic one dimensional two-object collision . momentum is conserved , but internal k.e is not conserved the objects stick together and so their final velocity is zero. I think this much help u...

Answer 2

Answer:

We have,

ABCD as the cyclic quadrilateral in which the diagonal AC and BD.

intersect each other at point P.

also, given that,

AB=8cm,

CD=5cm

Now,

In ΔDCA and ΔAPB,

We have

∠DCP=∠ABP

∠CDP=∠PAB

Hence, 

ΔDPC∼ΔAPB (by A.A property)

According to the given question,

arΔAPBarΔDPC=(ABDC)2

⇒24arΔDPC=(85)2

⇒24arΔDPC=6425

⇒arΔDPV=6425×24

arΔDPC=9.375cm2
