Answer #1

As per the data

Two Masses approach each other

Mass travelling to rigid directlion (M) =m1

​Mass travelling to right direction (M) =3m1

Velocity of bodies

u1 =5 m/s u2 =5m/s

Applying law of conservation of momentum

m1 u1 + m2 u2 =m1 v1 + m2 v2

As the two masses stick together v1 = v2 =v

Substiting Values

3m1 (5) + (5) m1 = 3 m1 (v) + m 1(v)

15 m1+ 5m1 =v (3m1 + m1)

20 m1 = v ( 4 m1)

Velocity =5 m/s

VELOCITY after the collission = 5 m/s

    Two pieces of clay are moving directly toward each other. When they collide, they stick together and move as one piece. One piece having mass 300 g is moving to the right at a speed of 1 m/s. The other piece has mass 600 g and is moving to the left at a speed of 0.75 m/s. a) Use momentum conservation to determine the velocity of the combined clay piece after they collide. (Note: you can treat this as a...

    One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 29 m/s. The masses of the two objects are 3.4 and 7.7 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is...
