Question

A cart changes its speed from 90 m/s to 100 m/s in 10 seconds. during this interval its acceleration is

Answer 1

the acceleration is 1

Answer 2

`1 (m)/(s^(2) )`

Step-by-step explanation:

Hello,I think I can help you with this

the acceleration is the change in the speed, in a given time. it can be calculated

`acceleration(a) =(speed_(f) -speed_(i) )/(time)\\\\`

Step 1

let

`\\speed_(f)=100\ (m)/(s) \\speed_(i)=90\ (m)/(s) \\time=10\ seconds\\`

put the values into the equation

`acceleration(a) =(100\ (m)/(s) -90\ (m)/(s) )/(10\ sec)\\\\acceleration(a)=(10 (m)/(s) )/(10\ seconds)\\acceleration(a)=1 (m)/(s^(2) )`

Have a nice day
