Acar accelerates from 21.0 m/s to 46.0 m/s in 2.5 seconds. what is the acceleration of the car.

Explanation:

The acceleration of an object is given by

where

v is the final velocity

u is the initial velocity

t is the time interval it takes for the velocity to change from u to v

For the car in this problem,

u = 21.0 m/s

v = 46.0 m/s

t = 2.5 s

Substituting, we find the acceleration

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

the closer the planet is to the sun, the larger the gravity
