Askier is gliding along at 3.0 m/s on horizontal, frictionless snow. he suddenly

The length of the inclined plane is 63.53 m and the time taken by the skier to cover the distance is 7.0588 sec.

Given to us

Velocity, u = 3.0 m/s

Angle of Inclination = 10"

Velocity of skier at the bottom, v = 15 m/s

We know that acceleration of the skier on the inclined plane can be given as,

a = g sin(θ)

a = g sin(10)

a= 9.81 x 0.1736

a = 1.70 m/sec²

We know that according to the third equation of motion

Substitute the values,

Using the first equation of motion,

Hence, the length of the inclined plane is 63.53 m and the time taken by the skier to cover the distance is 7.0588 sec.

acceleration of the skier on the inclined plane is given by

now by equation of kinematics

so the length of inclined plane will be 63.53 m

Part b)

Time to reach the bottom will be given by

so it will take 7.06 s to reach the bottom
