What is the equation for motion for a) free falling b) uniform retardationplease follow me friends please please. ​

Answer»

A) u would be zero as the object is not thrown there’s a free fall n the object was in rest earlier n when it was dropped it’s state changed to motion .v would be the final velocity
N a would be 9.8 m/s^2 that is the acceleration given by earth due to gravity
Time would be duration of the fall hence the equation would be v=u +at (where u would be zero n a would be 9.8 )
The equation remained the same u just entered the values if u would ENTER time then u can find out v as well
B) the equation is same here as well that is v =u +at u can ALSO use a=(v-u)/t they both r same though just WRITTEN DIFFERENTLY
So the equation would remain the same just the acceleration would be negative there fore u equation will be
V=u+(-a)t
Or
-a=(v-u)/t
