About 21c because it also depends on the weather outside
Answer:
Approximately
.
Explanation:
Assuming that there is no other force on this vehicle, the
force from the road would be the only force on this vehicle. The net force would then be equal to this
force. The size of the net force would be
.
Let
denote the mass of this vehicle and let
denote the net force on this vehicle.
By Newton's Second Law of motion, the acceleration of this vehicle would be proportional to the net force on this vehicle. In other words, the acceleration of this vehicle,
, would be:
.
For this vehicle,
whereas
. The acceleration of this vehicle would be:
.
It is more likely to be similar to his/her parents because the get half of their genetic code from their mom and half from their dad.
The answer would be D hope it helps and sorry if it is wrong. :)
Answer:
Explanation:
You have to declare which way is plus -- up or down. I will use down.
vi = - 2.85 The balloon is going up. That is the minus direction.
a = 9.81
d = 2.50 meters distance in this case is from the object to the ground.
d = vi*t + 1/2 a t^2
-2.50 = -2.85*t + 1/2 * 9.81 * t^2
-2.50 = -2.85*t + 4.905 * t^2 transfer the left to the right.
-4.905 t^2 + 2.85*t + 2.50 = 0
Use the quadratic formula to solve for t.
It turns out that t = 1.06
