In the winter sport of bobsledding, athletes push their sled along a horizontal ice surface and then hop on the sled as it starts to careen down the steeply sloped track. In one event, the sled reaches a top speed of 9.2 m/sm/s before starting down the initial part of the track, which is sloped downward at an angle of 4.0 ∘∘. What is the sled's speed after it has traveled the first 120 mm

Question

In the winter sport of bobsledding, athletes push their sled along a horizontal ice surface and then hop on the sled as it starts to careen down the steeply sloped track. In one event, the sled reaches a top speed of 9.2 m/sm/s before starting down the initial part of the track, which is sloped downward at an angle of 4.0 ∘∘. What is the sled's speed after it has traveled the first 120 mm?

Expert Solution
Step 1

Given speed on initial part of the track Vi=9.2m/s Vf=120mm or 0.12m.

And the angle of the slope =4°

We have to find the speed after it has traveled the first 120mm.

By conservation of energy the initial potential and kinetic energy of the sled is equal to the final kinetic energy of the sled.
