Question

a bullet of 20 gram is horizontly fired with a velocity of 150.0 meter per second from a pistol of mass 2 kg. what is the recoil velocity of the pistol​

Answer 1

Answer:

Have attached the answer. Have a look

Answer 2

GIVEN

• Mass = 20g = 0.02 kg
• Initial velocity (u) = 150 m/s
• Final velocity (v) = 0 m/s

SOLUTION

Distance travelled before coming to rest (s) = 10 cm=0.1 m

FORMULA USED

»» v² = u² - 2as « m«

⇒0=(150)² −2⋅a⋅0.1 = 112500 m/s²

»» f = ma ««

⇒f=0.02×112500 =2250 N
