Question

n astronaut has left the International Space Station to test a new space scooter. Her partner measures the following velocity changes, each taking place in a time interval 11.2 s . What are the average acceleration in each interval? Assume that the positive direction is to the right.

Answer 1

Answer:-

-1 m/s^2

Step-by-step explanation:

The average acceleration is given by dividing the change in velocity by change in time;

`a_f=(v_f-v_i)/(t_f-t_i)`

`=((0-11.2))/((11.2-0))=-1 m/s^2`

the point to be noted here is if the velocity is to the left we substitute it with a negative sign and if it is to the right we substitute it with a positive sign.
