Provided it Data: Mormontum of car = 1800 kgim/s Velocity of cas = 15m/s Find the mass of a car ?

Q: V 25° m 7 Fje v=const m = 5kg Find coof of friction mass is with constant velocity; MK = √₂

A:

Q: 1) What is the momentum of a car of mass 1850 kg m v and is moving at 27.75 h/s

A:

Q: a gun whose mass is 2.7kg fires a bullet of mass 20 grams at a speed of250m/s. compute the recoil…

A: Using the conservation of momentum, m1u1+m2u2=m1v1+m2v20=m1v1+m2v2                         u1=0,…

Q: Find momentum mass=0.651 kg Velocity=2.2 m/s

A:

Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.
