Say Yes or No:
Can an object reverse the direction of its motion even though it has constant acceleration?

Open in App
Solution

yes,
consider that velocity of object at any time t is given as
v(t)=t2
at t=0 sec, magnitude of |v|=2m/s (for war a direction)
also acceleration of object is
a(t)=dv(t)dt...(i)
=d(t2)dt=1m/s2
at t = 2
v(t)=t222
= 0m/s
however acceleration remains constant as that
of equation (1)
