Hello:) I need help with 2aii , thank you in advance!

Please see the attached picture.

(Draw a horizontal line anywhere above v=0.)

Explanation:

Zero acceleration means that the object is moving at a constant velocity (constant speed). It doesn't mean that it is at rest as it is still moving but at a constant speed of 5m/s, for example. At rest would mean that the speed is 0m/s, and the object is stationary.

Acceleration can be found by the gradient of the graph. To get an acceleration of zero, the line has to be a horizontal graph.

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.
