1. Marissa's car accelerates uniformly at a rate of 1269 . How long does
It take for Marisses car to accelerate from a speed of 24.5 m/stos speed
of 25.8 m/s ES 48

Answer 1

Answer: 1.02 s

Step-by-step explanation:

In this situation the following equation will be useful:

`V=V_(o)+at`

Where:

`V=25.8 m/s` is Marissa's car final velocity

`V_(o)=24.5 m/s` is Marissa's car initial velocity

`a=1.269 m/s^(2)` is Marissa's car constant acceleration (assuming this is the acceleration, since 1269 m/s^{2} does not make sense)

`t` is the time it takes to accelerato from
`V_(o)` to
`V`

Isolating
`t`:

`t=(V-V_(o))/(a)`

`t=(25.8 m/s-24.5 m/s)/(1.269 m/s^(2))`

`t=1.02 s`
