during a space shuttle launch about 830,000 kg of fuel is burned in 8 min. the fuel provides the shuttle with a constant thrust,

or forward force. how does newton's second law of motion explain why the shuttle's acceleration in creases as the fuel is burned?

The shuttles acceleration in the creases as the fuel is burned because the acceleration of the obect as produced by net force is directly proportional to the magnitude of the net force.

[Assume g = 10m/s?] If a girl is running along a straight road with a uniform velocity 1.5 m/s, find her acceleration. (Ans: 0)
DerKrebs [107]

Answer:

Her acceleration is 0 m/s²

Explanation:

We note that the motion of the girl is on a straight road, therefore;

The vertical acceleration (e.g. due to gravity, <em>g)</em> on the horizontal motion = 0

The horizontal acceleration, a = (Change in velocity, Δv)/(Change in time, Δt)

For uniform velocity, the change in velocity, Δv = 0

Therefore, fore any change in time, Δt, we have;

a = Δv/Δt

Her acceleration, a = 0/Δt = 0

Her acceleration, a = 0 m/s²

You have two golf balls that differ only in their surfaces. one has dimples, while the other is smooth. if you were to drop the
il63 [147K]

Answer: the golf ball with smooth surface would hit the ground first.


Jusitification:


An analysis of forces show two vertical forces acting on the golf balls.


1) one force is the weight (mg) which is vertical downward


2) the other force is the drag force exerted by the air on the golf balls, and it is vertical upward.


3) the drag force opposes the weight, so the acceleration downward is determined by the difference of the weiight and the drag force, until the balls reach the terminal speed (when the drag force equals the weight).


4) the drag force depends on the shape and area of the object falling. Being the surface of one ball smooth implies that the drag force will be less than the one on the other ball.


5) less drag force implies that the terminal velocity of the smooth ball will he higher, ant then it will hit the ground first.

The velocity of a car teduces from 30 km/h as the car approaches a stop sigh. Is this an example of positive or negative acceler
tresset_1 [31]

<u>Answer:</u>

The stopping car has negative acceleration.

<u>Explanation:</u>

 We know acceleration is the rate of change of velocity. That is

            Acceleration(a) = ( Final velocity - Initial velocity )/ Time taken.

            Here Final velocity = 0 km/h( car stops) and initial velocity = 30 km/h

             So acceleration = (0-30)/time = -30/ time

             Time is always positive , so -30/time is negative, so the stopping car has negative acceleration.
