.A car skid for 290 m. assuming that the car skidded to a stop with a constant
snow_tiger [21]

Answer:

The speed of the car before it began to skid is 47.56 m/s.

Explanation:

We can use kinematics to solve this problem.

We are given three known variables:

  • Δx = 290 m
  • a = -3.90 m/s²
  • v = 0 m/s (final velocity is 0 m/s because the car skids to a stop).

We can use this kinematic equation to <u><em>solve</em></u><em> for the initial velocity</em>, v₀.

  • <u>v² = v₀² + 2aΔx</u>

Substitute the known variables into the equation.

  • (0)² = v₀² + 2(-3.9)(290)
  • 0 = v₀² - 2262
  • 2262 = v₀²
  • <u>v₀ = 47.56 m/s</u>

The speed of the car before it began to skid is 47.46 m/s.

Scilla [17]

Answer:

Explained.

Explanation:

Let me explain the two cases in by one.

(1) When Person wearing a jacket, heat from his or her body is going to get trapped inside his or her jacket to keep this person warm when a thermometer is placed inside, it would indicate a higher temperature on the scale.

(2) When Jacket is Hanging in a closet, its temperature would be roughly close to room temperature and when we would place a thermometer it would not indicate any change on its scale.
