If an object is moving at #4 m/s# and accelerates to #6 m/s# over 3 seconds, what was the object's rate of acceleration?

Answer 1

Sebastian Acosta

#a=2/3 m/s^2#

#v_i=4 m/s" initial velocity of object"#

#v_l=6 m/s" last velocity of object"#

#t=3 s#

#a=?" acceleration of object"#

#"the object's rate of acceleration is given as "a=(Delta v)/(Delta t)#

#Delta v=v_l-v_i=6-4=2 m/s#

#Delta t=3-0=3#

#a=2/3 m/s^2#

The object's rate of acceleration is ( \frac{2}{3} ) m/s².

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
