the third answer is right.
It must be either speeding up, or slowing down, or turning. There are no other possibilities.
Answer:
S = V0 t + 1/2 a t^2
S = 5 m/s * 300 s + 1/2 * 1.2 m/s * (300 s^2)
S = 1500 m + .6 * 90000 m = 55,500 m
Check: V0 = 5 m/s
V2 = V0 + a t = 5 + 1.2 * 300 = 365 m/s
Vav = (V1 + V2) / 2 = (5 + 365) / 2 = 185 m/s (note uniform motion)
S = 185 * 300 = 55,500 m
We calculated V2 above at 365 m/s the speed after 300 sec
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:
.
Answer:
Executive Orders state mandatory requirements for the Executive Branch, and have the effect of law. They are issued in relation to a law passed by Congress or based on powers granted to the President in the Constitution and must be consistent with those authorities.
