Calculate the acceleration of a car that can go from rest to 100 km/h in 10 seconds

Physics
1 answer:
Basile [38]3 years ago
8 0

Answer: 2.77 m/s^{2}

Explanation:

Acceleration a is defined as the variation of velocity \Delta V with time \Delta t:

a=\frac{\Delta V}{\Delta t}

Where:

\Delta V=100km/h-0km/h=100km/h=27.77m/s

\Delta t=10 s

a=\frac{27.77m/s}{10 s}

Finally:

a=2.77m/s^{2}

Answer:

1. Who gathered the data that showed planets traveling in elliptical paths around the sun?

2. Who discovered elliptical orbits?

3. Who explained them?

Explanation:

1. Tycho Brahe was the one that gathered data.


2. Johannes Kepler discovered it using Tycho Brace’s Data.


3. I believe it was Johannes Kepler because he created 3 laws of it.


I apologize if it is incorrect-

Gnom [1K]

Answer: The elimination of seasonal variations

Explanation:

Since the cosmic catastrophic event which occurred led to the tilt of the Earth's axis relative to the plane of orbit to increase from 23.5° to 90°, the most obvious effect of this change would be the elimination of seasonal variations.

It should be noted that seasonal variation refers to the variation in a time series that's within a year which is repeated. The cause of seasonal variation can include rainfall, temperature, etc.

Find the velocity. 10 points. Will give brainliest!
BARSIC [14]

Answer:

6.060606...

Explanation:

To figure out velocity, you divide the distance by the time it takes to travel that same distance, then you add your direction to it. So the distance would be 1000m and the time would be 2 minutes and 45 seconds and if you convert the minutes into fractions you would get 165 seconds than you would divide 1000m by 165 seconds and you would get 6.060606... seconds as her average velocity

A karate master strikes a board with an initial velocity of 10.0 m/s, decreasing to 1.0 m/s as his hand passes through the board
kenny6666 [7]

The force exerted on the board by the karate master given the data is -4500 N

<h3>Data obtained from the question </h3>
  • Initial velocity (u) = 10 m/s
  • Final velocity (v) = 1 m/s
  • Time (t) = 0.002 s
  • Mass (m) = 1 Kg
  • Force (F) = ?
<h3>How to determine the force</h3>

The force exerted can be obtained as illustrated below:

F = m(v - u) / t

F = 1 (1 - 10) / 0.002

F = (1 × -9) / 0.002

F = -4500 N
