at t=T/6, total distance covered= 2*pi*r/6  and  displacement= r

 difference of them = 2*t
so, 2*pi*r/6- r =2(1/6)=1/3

r=1/(pi-3)=7.062

) A skier starts down a frictionless 32° slope. After a vertical drop of 25 m, the slope temporarily levels out and then slopes
EastWind [94]

Answer:

The skier’s speed on the two level stretches are 22.13 m/s and 27.29 m/s.

Explanation:

Given that,

Slope down = 32°

Height = 25 m

Before leveling,

Slope down = 20°

Height = 38 m

We need to calculate the skier’s speed on the two level stretches

Using formula of energy

P.E=K.E

mgh=\dfrac{1}{2}mv^2

v=\sqrt{2gh}

For first stretch,

Height = 25 m

Put the value into the formula

v=\sqrt{2\times9.8\times25}

v=22.13\ m/s

For second stretch,

Height = 38 m

Put the value into the formula

v=\sqrt{2\times9.8\times38}

v=27.29\ m/s

Hence, The skier’s speed on the two level stretches are 22.13 m/s and 27.29 m/s.
