Want this question answered?
v = u + at so 27 = 0 +a10 thus (27-0)/10 = a Acceleration = 2.7 m.s-2
no
a body projected upward is in rest at the top most point, but acceleration is not zero
To come to rest, its velocity must change, therefore it will accelerate. Once it is at rest, if it remains at rest, it will no longer accelerate, i.e., its acceleration will be zero.
0.95 - 1.05 secs
velocity = acceleration x time 27 = acceleration x 10 acceleration = 2.7 m/sec/sec
v = u + at so 27 = 0 +a10 thus (27-0)/10 = a Acceleration = 2.7 m.s-2
My car can reach a maximum speed of 150km/hr. And my car can acclerate at 5km/hr2. How long will it take for my car to reach 150km/hr from rest?
No a boday while rest cannot be in acceleration because of the momentum of the body ...........................
no
zero
Zero
