Answer:
c) heat
Explanation:
steam has more heat energy than boiling water due to its latent heat of vaporisation.
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.
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.
The answer is B. You divide 717 by the acceleration by gravity of earth (9.8 m/s) and divide 5320 by your answer.
