Question

Please some one ans. The last question of the pic above

Answer 1

Answer:

v = 400 m/s

u = 0

t = 0.004 s

m = 10 g = 0.01 kg

acceleration = v-u/t = 400/0.004 = 100000 m/s^2

force = mass x acceleration = 0.01 * 100000

= 10000 N

Answer 2

Answer:

v = 400 m/s

u = 0

t = 0.004 s

m = 10 g = 0.01 kg

acceleration = v-u/t

= 400/0.004

= 100000 m/s^2

force = mass × acceleration

0.01 × 100000

= 10000N
