Question

A machine gun fires 60 bullets per minute with a velocity of 700m/s. If each bullet has a mass of 50g, find the power developed by the gun.?

is the answer
24500w plz tell

Answer 1

P= nKE÷t
P=60×0.5×5×7×7×100×1÷60
P=12250 watt

Answer 2

Dear Student,

● Answer -

Power = 12250 watt

◆ Explanation -

# Given -

v = 700 m/s

m = 50 g = 0.95 kg

n/t = 60 bullets/min = 1 bullet/s

# Solution -

The power developed by the gun is given by formula -

Power = Work done / time

Power = n × (1/2 mv^2) / t

Power = n/t × 1/2 × mv^2

Power = 1 × 1/2 × 0.05 × 700^2

Power = 12250 watt

Hence, the power developed by the gun is 12250 watt.

Thanks dear. Hope this helps you...
