Answer:
1.51783893986
Explanation:
One kilogram is equal to 9.81 Newtons
You have 14.89N, divide this by 9.81 and u get the mass in KG
so u do 14.89/9.81 = 1.51783893986 or 1.52kg (2dp)
Answer: 1m/s
Explanation: according to the law of conservation of linear momentum in an isolated system, the momentum of the gun equals that of the bullet.
Mathematically
Mb×Vb = Mg×Vg
Where Mb = mass of bullet = 1/100 = 0.01 kg
Vb = velocity of bullet = 200 m/s
Mg = mass of gun = 2kg
Vg = recoil velocity of gun =?
0.01×200 = 2×Vg
Vg = 0.01×200/2
Vg = 0.01×100
Vg = 1m/s
Answer:
speed and velocity, c would be my guess
