While leunching a rocket a rocket of mass `2xx 10^(2) kg` , a force of `5 xx 10^(5)` . N is applied for 10 seconds . What is the velocity attained by the rocket at the end of `10 s` ?

While launcing a rocket of mass 2 xx10^(4) kg, a force of 5 xx10^(5) N is applied for 20 s. Calculate the velocity attained by the rocket at the end of 20 s.

While lauching a rocket of mass 2xx 10^(4)kg a force of 5 xx 10^(5) N is applied for 20s Calculate the velocity attained by the rocket at the end of 20s .

The mass of ship is 2 xx 10^7 kg. On applying a force of 25xx10^5 N, it is displaced to 25 metres, the speed of ship is

. The mass of a ship is 2 xx 10^7 kg. On applying a force of 25 xx 10^5 N, it is displaced through 25 m. The speed of ship is

A Rocket having initial mass 5xx10^(6)kg , which include mass of fuel of mass 4xx10^(6)kg is ejecting gas with velocity 4000m//s relative to Rocket when entire fuel finishes?

A rocket burns 0.5 kg of fuel per second ejecting it as gases with a velocity of 1600 m//s relative to the rocket . How much force is exerted on the rocket ? Also , calculate the velocity attainted by the rocket , when its mass reduces to (1)/(200) th of its initial mass .

A Rocket having initial mass 5xx10^(6)kg , which include mass of fuel of mass 4xx10^(6)kg is ejecting gas with velocity 4000m//s relative to Rocket. Then what will be the velocity of rocket when entire fuel finishes?

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 .
