Question

Q2 a rifle bullet of mass 50 gram travelling at a speed of 200 m/s. Find the kinetic energy of the bullet.​

Answer 1

Answer:

Mass= 50 grams=0.05 kg

Speed= 200m/s

K.E= 0.5×0.05×(200)²

=1000 Joules

Answer 2

Mass = 50g

speed = 200m/s

KE = 1/2 mv^2

1/2×50×(200)^2

25 × 40000

1000000 j
