Discuss the relationship between size and wieght of an object and the amount

The wieght is the measure of the force of gravity on an object's mass, while mass is the measure of how much matter there is in an object. An object's weight is calculated as the mass of an object in kilograms multiplied by the acceleration of gravity exerted in meters per second squared.

u2 = 0.897 m/s

Explanation:

Note: Question is incomplete ( upon the missing of velocity of the 0.300 kg puck after collision -- i have tried to find as below)

Let the left Puck mass at rest = m1 =0.300 Kg

mass of the right puck m2 = 0.200 kg

velocity of m1 before collision v1= 2.00 m/s

velocity of m2 before collision v2 = 0m/s

velocity of m1 after collision u1 =1.00 m/s

velocity of m2 after collision u2 = ? m/s

θ = 52°

Solution:

Before collision:

Momentum (y-axis ) before collision= 0 Kgm/s

Momentum (x-axis ) before collision= m1v1 + m2v2 = 0.300 Kg x 2.00 m/s + 0

= 0.600 Kgm/s

After collision:

Momentum (y-axis ) after collision= m1u1 sinθ  + m2u2 sinθ

= 0.300 x 1.00 m/s sin 52 °  + 0.2 x u2 sin 52°

= 0.236 + 0.158 u2

Momentum (x-axis ) after collision= m1u1 cosθ  + m2u2 cos θ

= 0.300 x 1.0 m/s cos 52 ° + 0.200 x u2 cos 52°

= 0.184 + 0.123 u2

According to law of conservation momentum

momentum before collision = momentum after collision.

0 + 0.60 Kgm/s =  0.236 Kgm/s  + 0.158 kg u2 + 0.184 Kgm/s + 0.123 kg u2

0.672 Kgm/s = 0.420 Kgm/s + 0.281 u2

u2 = 0.897 m/s
