The net force versus time graph of a rocket is shown in figure The mass of the rocket is `1200kg`. Calculate velocity of rocket, 16 seconds after starting from rest. Neglect gravity.

A rocket is fired upwards. Its velocity versus time graph is shown in the figure-1.131. The maximum height reached by the rocket is:

A rocket motor consumes 100 kg of fuel per second exhausting it with a speed of 6 xx 10^(3) ms^(-1) What thrust is exerted on the rocket ? What will be the velocity of the rocket at the instant its mass is reduced to (1 // 40) of its initial mass ? Take initial velocity of rocket as zero . Neglect gravity .

A rocket is ejecting a mass m of gases per unit time with velocity V relative to the rocket, the thrust on the rocket is:

A rocket is ejecting 1 kg of gases per sec at a velocity of 60 km/s. The accelerating force on the rocket is

Fuel is consumed at the rate of 50 kg s^(-1) in a rocket. Find the thrust on the rocket if the velocity of the exhaust gases is 2 km s^(-1) . Also calculate the velocity of the rocket at the instant, when its mass is reduced to l/10th of its initial mass if its initial velocity is zero, (neglect gravity)
