Consider the inelastic collision. Two lumps of matter are moving directly toward each other. Each lump has a mass of 1.500 kg 1.500 kg and is moving at a speed of 0.930 c 0.930c . The two lumps collide and stick together. Answer the questions, keeping in mind that relativistic effects cannot be neglected in this case. What is the final speed v f vf of the combined lump, expressed as a fraction of c ?

The final velocity after impact of the combine lump is

V=0.930m/s

Explanation:

Step one

This type of collision is an inelastic types of collision. The total energy of the colliding bodies is conserved or when the bodies stick together and move with a common velocity

Step two

Given data

M1= 1500kg

M2=1500kg

U1=0.930m/s

U2=0.930m/s

V= ?

Step three

Applying momentum equation we have

Total momentum before impact

=M1U1+M2U2

Total momentum after impact

=(M1+M2) V

According to the principle of conservation of momentum

M1U1+M2U2=(M1+M2) V

Substituting our data into the expression we have

1500*0.930+1500*0.930=

(1500+1500)V

1395+1395=3000V

2790=3000V

V=2790/3000

V=0.930m/s

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
