Question

please tell me friends ​

Answer 1

Answer:

Hey Mate! Here is your Answer:

Explanation:

Mass of bullet = 10g =0.01kg

velocity of bullet =1.5 m/8

Mass of Plank =90g =0.09kg

Total momentum before collision = mass of plank × velocity

= 0.01×1.5 + 0.09×0 = 0.015 kg m/8

Total momentum after collision = (mass of bullet + mass of Plank)× Velocity

=0.1kg × v = 0.1 V kg m/8

According to law of conservation of moment,

Total momentum before collision = Total momentum after collision

= 0.015 kg m/8=0.1 v kg m/8

velocity acquired by the plant and the bullet = 0.15 m/8

Answer 2

Answer:

mass of bullet = 10g= 0.01kg

velocity of bullet = 1.5 m/s

mass of plank =90g=0.09kg

Total momentum before collision =mass of plank × velocity

= 0.01×1.5 + 0.09 × 0 = 0.015kg m/s

Total momentum after collision =(mass of bullet + mass of plank ) × velocity

= 0.1kg × v=0.1v kg m/s

According to law of conservation of momentum.Total momentum before collision = Total momentum after collision

0.015kg m/s = 0.1v kg m/s

velocity acquired by the plank and the bullet=0.15m/s .
