WebAug 5, 2012 · A bullet of mass 10 g moving with a velocity of 400 m/s or a cricket ball of mass 400 g thrown with the speed of 90 km/hr. Answer : Momentum (P) = mass (m) × velocity (v). mass of bullet = 10g = 10 × 10 -3 kg = 10 -2 kg velocity of bullet = 400 m/s momentum of bullet = 10 -2 kg × 400 m/s = 4 kg m/s WebApr 7, 2024 · The bullet of mass m is fired with forward velocity v. The gun of mass M acquires a backward velocity u. Before firing, the total momentum is zero so that the total momentum after firing is also zero. 0 = mv + Mu. u = -\[\frac{m}{M}\]v. u is the recoil velocity of the gun. The mass of the bullet is much less than that of the gun i.e. m ≪ M.

WebJun 2, 2024 · From a rifle of mass 4 kg, a bullet of mass 50 g is fired with an initial velocity of 35 m/s. calculate the initial recoil velocity of the rifle. (class 9th) (3 marks) See answers Advertisement Brainly User ANSWER : ( m₁ ) Mass of rifle = 4kg ( m₂ ) Mass of bullet = 50g = 0.05kg ( v₂ ) Velocity of bullet = 35 m/s ( v₁ ) Recoil velocity of rifle = ? WebFind the velocity of the car with mass 4 kg with respect to ground. Ans: Given, m 1 = 4 kg m 2 = 10 kg v 1 = ? v 2 = 5 m.s -1 P initial = 0, as the cars are at rest P final = p 1 + p 2 P final = m 1 .v 1 + m 2 .v 2 = (4 kg). (v 1) + (10 kg). (5 m.s -1) We know from the law of conservation of momentum that, P initial = P final king richard iii scoliosis
