A bullet of mass 0.1 kg moving horizontally with a velocity of 20 m/s strikes a target and brought to rest in 0.1 s.
Given: m = 0.1 kg, u = 20 m/s, t = 0.1 s To find: Impulse (J), Average force (F) Formulae: i. J = mv – mu ii. F = \(m\frac{(v-u)}{t}\) Calculation: From formula (i). J = m(v...

A bullet of mass 10 g is fired from a gun of mass 1 kg with recoil velocity of gun = 5 m/s. The muzzle velocity will be
Correct option is: (D) 500 m/s Using conservation of linear momentum. \(m_1 \ v_1 = m_2 \ v_2\) \(v_1 = \frac{m_2 \ \times \ v_2}{m_1}\) \(v_1 = \frac{1 \times 5}{10 \times 10^{-3}}\) \(v_1 = \frac{5000}{10}\) \(v_1 =...
