Four different objects are placed on a number line at 0. The chart describes the motion of each object. Object
Motion
w
3 units left, then 3 units right
X
6 units right, then 18 units right
Y
8 units left, then 24 units right
Z
16 units right, then 8 units left
Using the information in the chart, the distance and displacement of each object can be determined. Which object has
a distance that is three times as great as its displacement?
w
OX
Ο Υ
Oz

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

it is a negative acceleration

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.
