A spacecraft headed to Mars has fired its engines and accelerated from rest until has escaped Earth's gravity. The spacecraft
reaches a planned speed and then turns the engines off. At this point, in space, which graph bests represents the motion of the
spacecraft?

not too sure thinking all accelerations are pointed down

conservation of mass

mass before something happens = mass afterwards

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
