Answer to Question #717 in Mechanics | Relativity for Rooky
Can you show work please?
equations of motion of a body in constant acceleration is:
Where v is the final velocity and v0 is the initial velocity and v0 = 0. Now with all the data we have, we can get for the final velocity:
For the distance the car traveled in that time, we use another one of the equations of motion of a body in constant acceleration, namely the time-independent one:
and since v0 = 0 we get Δx=v²/2a
and using the data we have, we get Δx=v²/2a=30²/2*5=900/10=90m
We could nd the distance by another method, using another equation of motion:
