Im having trouble with this problem. Can someone break it down for me please? Model rockets...
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...
Model rockets are fun. These tiny engines (about the size of your little finger) that fire for around 2 seconds and have a surprising thrust! Your rocket has a mass of 0.5 kg and you want to know its maximum speed! You place the rocket, count down, light the fuse, and away it goes! Using a nifty radar gun, you measure the velocity of the rocket to be 47 m/s the moment the engine runs out of fuel. Calculate the...
Im having trouble with this question. Can someone break this down to me? You roll out of bed in the morning. Typically beds are 0.5 m off the ground. What is the magnitude of the average force you will experience once you hit the floor if the collision tales 0.1 seconds. You may assume a mass for the average person is 65kg. A. 6370 N B. 2035 N C. 1018 N D. 3185 N
