Fuel is consumed at the rats of 100kg//s in a rocket The exhaust gases are ejected at a speed of 4.5 xx 10^(4) ms^(-1) w.r.t the rocket What is the thrust experienced by the rocket Also calculate velocity of the rocket at the instant when its mass is reduced of rocket to be zero .

A rocket consumes 24kg of fuel per second The burnt gases escape the rocket at a speed of 6.4km//s relative to the rocket Calculate the upthrust recevied by the rocket Also calculate the velocity acquired by the rocket when the mass redues to 1//100th of its initial mass.

A bicycle initially moving with a velocity 5.0 ms^(-1) accelerates for 5 s at a rate of 2 ms^(-2) . What will be its final velocity?

A rocket moves in the absence of external forces by ejecting a steady jet with velocity u constant relative to the rocket. Find the velocity v of the rocket at the moment when its mass is equal to m, if at the initial moment it possessed the mass m_0 and its velocity was equal to zero. Make use of the formula given in the foregoing problem.

Fuel is consumend at the rate of 50 g per second in a rocket. The exhaust gases are rejected at the rate of 5xx10^(5)cms^(-1) . What is the thrust experienced by the rocket?

A 2000 kg rocket in free space expels 0.5 kg of gas per second at exhaust velocity "400 m s"^(-1) for 5 s. The increase in the speed of the rocket in this time is
