A rocket is fired in deep space, where gravity is negligible.

If the rocket has an initial mass of 6500 kg and ejects gas at arelative velocity of magnitude 1900 m/s, how much gas must it ejectin the first second to have an initial acceleration of 24.0m/s^2?

please help figure out this question, teacher never taught ussomething like this. Thanks in advance


A ball of mass .0750kg is traveling horizontally with a speed of2.20 m/s. It strikes a vertical wall and rebounds horizontally. Dueto the collision with the wall, 20% of the ball's initial keneticenergy is dissipated.

A:Show that the ball rebounds from the wall with a speed of 1.97m/s^-2

For this part i assumed that the ^-2 was a typo and was meant tojust be ^2.
However, my work is wrong and my teacher never taught us thisinformation. What i did was divided the initial speed of 2.20M/s by.8 since it losses 20% of its energy when it hits the wall,however, this give you an answer of 1.76 m/s. can someone show mehow to do this correctly or show me where i went wrong?
