An object moving at 40 m s–1 decelerates steadily at 2.8 m s–2 . Calculate: a) the distance travelled by the object before it comes to rest b) the time it takes to stop c) the displacement it travelled during the last 2 seconds​

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

a is the best answer your welcome
