Calculating Acceleration of a Car
Acceleration Calculation
A car accelerates uniformly from rest to a speed of 10m/s. We can calculate its acceleration using the following formula:
Acceleration (a) = Change in velocity / Time taken
Given that the car starts from rest, the initial velocity (u) is 0 m/s. The final velocity (v) is 10 m/s. Therefore, the change in velocity is:
Change in velocity = Final velocity - Initial velocity
Change in velocity = 10 m/s - 0 m/s = 10 m/s
Now, if the time taken for the car to reach this speed is t seconds, we can substitute the values into the formula for acceleration:
Acceleration = 10 m/s / t
Acceleration = 10 / t m/s2
Therefore, the acceleration of the car is 10/t m/s2.
Give four examples of landforms where both the water and the land around it are flat. Flat landforms where both the water and the land around it are flat include: 1. Coastal plains: These are flat areas of land near the coast that are also accompanied by shallow waters. 2. Lagoons: Lagoons are shallow bodies of water separated from the sea by sandbars or barrier islands and are often surrounded by flat land. 3. Salt flats: These are large, flat expanses of land covered with salt and other minerals where water collects and evaporates, leaving a flat surface. 4. Tidal flats: These are areas of land that are submerged and exposed by the tides, creating flat mudflats that are covered and uncovered by water regularly.
