Areindeer needs to pull a sleigh up a 30 degree incline. if the mass of the sleigh is 200 kg, and the coefficient of kinetic friction between the sleigh and the incline is 0.2, what speed will the sleigh have when it reaches the top of the incline? assume the height of the incline is 10m.

v = 26.94 m/s

Explanation:

given,

angle of inclination = 30°

mass of the sleigh = 200 kg

coefficient of kinetic friction = 0.2

height of inclination = 10 m

pull force be = 5000 N

now,.

L = 20 m

v² = u² + 2 as

v² = 0 + 2 x 18.14 x 20

v = 26.94 m/s

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

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.
