Answer #1

By Newton's second law:

F = ma

=> a = F/m

= (3.75*10^10 N)/(2.75*10^10 kg)

= 1.36 m/s^2

Given t = 8s

Use: v = at

= 1.36 * 8

= 10.9 m/s

    Model rockets have tiny engines that fire for around 2 seconds. Your rocket has a mass of 0.5 kg and you want to know its maximum speed. Using a radar gun you measure the velocity of the rocket to be 47 m/s the moment the engine runs out of fuel. Calculate the force this engine exerts on your rocket. Hint: There are two forces in play here that give each their own accelerations to the rocket. You observe a NET...
