Question

A rocket is ejecting 1 kg of gas per secong at velocity of 60 km/s.the accelarating force on rocket is ____________________________

Answer 1

Mass ejection rate = 1 kg/s
Velocity of ejected mass = 60km/s = 60000 m/s

Accelerating force = 1×60000 kg.m/s^2 = 60000 N = 60 kN

The accelerating force on rocket is 60kN

Answer 2

Answer:

The accelerating force on rocket is 60 kN

Explanation:

Given that,

The mass of gas ejected = 1 kg/s

Velocity = 60 km/s = 60000 m/s

Force = mass of ejected ges per second ×  Velocity of ejected gas

$F = 1\times60000$

$F = 60000\ N$

$F = 60\ kN$

Hence, The accelerating force on rocket is 60 kN.
