A car traveling at 25 meters per second is brought to stop by a force over a 10 second timer interval. What was the acceleration of the car during the 10 second time interval.

–2.5 m/s²

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 25 m/s

Final velocity (v) = 0 m/s

Time (t) = 10 s

Acceleration (a) =?

Acceleration can simply be defined as the rate of change of velocity with time. Mathematically, it can be expressed as:

a = (v – u) /t

Where:

a => is the acceleration

v => is the final velocity

u => is the initial velocity

t => is the time.

With the above formula, we can obtain the acceleration of the car as follow:

Initial velocity (u) = 25 m/s

Final velocity (v) = 0 m/s

Time (t) = 10 s

Acceleration (a) =?

a = (v – u) /t

a = (0 – 25) /10

a = –25 / 10

a = –2.5 m/s²

The acceleration of the car is –2.5 m/s². The negative sign indicate that the car is decelerating i.e coming to rest.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
