Question

The engine of a jet aircraft applies a thrown force of 10 n during take off and causes the plane to attain a velocity of 1km/s in 10 s. The mass of the plane is

Answer 1

Hey Dear,

◆ Answer -

m = 0.1 kg

◆ Explaination -

# Given -

F = 10 N

v = 1 km/s = 1000 m/s

t = 10 s

# Solution -

Applying Newton's 2nd law of motion -

F = m.a

F = m × (v-u)/t

m = F.t / (v-u)

m = 10 × 10 / (1000-0)

m = 100 / 1000

m = 0.1 kg

Therefore, mass of plane is 0.1 kg.

Thanks dear...
