A rocket has a per-ignition mass of 1100kgs-1 producing a thrust of 10000N. How long after ignition of the fuel will the rocket lift off? also explain how is it possible for a rocket to accelerate in space. (i cant work it outt. i know it involves the roc...

(ignore the other question i posted this is the right one) A rocket has a pre-ignition mass of 1100kg. On ignition it burns fuel at rate of 20kg s-1 producing a thrust of 10000N. How long after ignition of the fuel, will the rocket lift off? also explain...

A driver has 50kg mass, and drives from a high board. On entering the water the driver travels vertically downward and comes to rest in a vertical distance of 5 m. The average resistance force is acting on the driver during the motion to rest in the water...

A block of mass 0.229 kg is placed on top of a light, vertical spring of force constant 4665 N/m and pushed downward so that the spring is compressed by 0.093 m. After the block is released from rest, it travels upward and then leaves the spring. To what...

The question says : the gradient of a curve is give by dy/dx = x^2 - 6x. Find the set of values of x for which y is an increasing function of x. I didn't understand what they are asking me to do could you solve and explain?

i haveeee!! ive posted the right question again please look it up again if you have time :(

ahh thank you so much! can you write the actual formulas that you've used because im not sure if i understood it correctly

thank youuuuu!

mwahahahahahaaa i worked it out myselfff:D 1/2 kx^2 = mgh 1/2 (4665)( 0.093)^2 = (0.229)(9.81)h 9.02m =h

butthead is right, it still works for 2021
