Answer:
Acceleration ( a ) = -2.25 m/s^2
Explanation:
Given data :
Initial velocity ( u ) = 15 m/s
Distance ( s ) = 50 m
Final velocity ( v ) = 0 m/s
By applying the third equation of motion ,
v^2 - u^2 = 2as
-225 = 2*a*50
Thus ,
a = - 2.25 m/s^2
( Note : We have a negative answer as the bike is retarding )
