A car traveling at 7 m/s accelerates at 2,5 m/s2 to reach a speed of 12 m/s. How long does it take for this acceleration?

The car took 2.5 seconds for this acceleration

Explanation:

Constant Acceleration Motion

It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.

Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

Solving for t:

The car was traveling at v0=7 m/s, accelerated at 2.5 m/s^2, and reached a speed vf=12 m/s. Calculating the time taken:

t=2 sec

The car took 2 seconds for this acceleration

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.

answer: he got 23
