a body of mass 25 gram has a momentum of 0.40 kg metre per second find its kinetic energy
Answers
Answer:
Mass of the body = 25g
Mass of the body = 25g =25/1000 kg
Mass of the body = 25g =25/1000 kg = 0.025kg
Mass of the body = 25g =25/1000 kg = 0.025kgMOMENTUM =0.40kg
Mass of the body = 25g =25/1000 kg = 0.025kgMOMENTUM =0.40kgBut momentum =mass X velocity
Mass of the body = 25g =25/1000 kg = 0.025kgMOMENTUM =0.40kgBut momentum =mass X velocity p=m X v
Mass of the body = 25g =25/1000 kg = 0.025kgMOMENTUM =0.40kgBut momentum =mass X velocity p=m X vtherefore 0.40kg=0.025kg X v
Mass of the body = 25g =25/1000 kg = 0.025kgMOMENTUM =0.40kgBut momentum =mass X velocity p=m X vtherefore 0.40kg=0.025kg X vv=0.40/0.025 m/s
Mass of the body = 25g =25/1000 kg = 0.025kgMOMENTUM =0.40kgBut momentum =mass X velocity p=m X vtherefore 0.40kg=0.025kg X vv=0.40/0.025 m/sv=16 m/s
Mass of the body = 25g =25/1000 kg = 0.025kgMOMENTUM =0.40kgBut momentum =mass X velocity p=m X vtherefore 0.40kg=0.025kg X vv=0.40/0.025 m/sv=16 m/sAs KINETIC ENERGY =1/2mvsquare
Mass of the body = 25g =25/1000 kg = 0.025kgMOMENTUM =0.40kgBut momentum =mass X velocity p=m X vtherefore 0.40kg=0.025kg X vv=0.40/0.025 m/sv=16 m/sAs KINETIC ENERGY =1/2mvsquaretherefore K. E =1/2x0.025x16x16
Mass of the body = 25g =25/1000 kg = 0.025kgMOMENTUM =0.40kgBut momentum =mass X velocity p=m X vtherefore 0.40kg=0.025kg X vv=0.40/0.025 m/sv=16 m/sAs KINETIC ENERGY =1/2mvsquaretherefore K. E =1/2x0.025x16x16K. E = 6.4/2
Mass of the body = 25g =25/1000 kg = 0.025kgMOMENTUM =0.40kgBut momentum =mass X velocity p=m X vtherefore 0.40kg=0.025kg X vv=0.40/0.025 m/sv=16 m/sAs KINETIC ENERGY =1/2mvsquaretherefore K. E =1/2x0.025x16x16K. E = 6.4/2K. E =3.2 m /s
