Question

A Review Constants Periodic Table Part A You are driving your 1400 kg car at 19 m/s down a hill with a 5.0° slope when a deer suddenly jumps out onto the roadway. You slam on your brakes, skidding to a stop. How far do you skid before stopping if the kinetic friction force between your tires and the road is 1.1x104 N ? Solve this problem using conservation of energy. Express your answer with the appropriate units. μΑ 2) ? d = Value Units Submit Request Answer

Answer 1

The initial mechanical energy is lost to friction while skidding down the slope. We use this to find the required distance as shown below

Let it skids a height h below its initial position. Let gravitational PE be zero at final position So, initial energy = mgh + 2 / 2 mu? E h = dsino 5° So, energy lost to E Now, - friction is Ei work done by friction = might I move? fd =) madsino + 1 move? - 2 min = fd > (240019) (9.8 m/s2) asins°) + (140019) (49 m/s)? = (1.24204N) => ا11 d = 25.81 m.
