The correct answer would be D. A new experiment would be needed to be done in order to test the conclusions. In science there is no authority, data is the only thing that matters. So if we have two different conclusions from the same date the only solution is to perform more tests and more experiments to see what is correct.
8.0 m/s if there is no air resistance. (B)
Less if there IS any air resistance.
Answer:
Maximum acceleration will be equal to
Explanation:
We have given coefficient of kinetic friction
And coefficient of static friction
Acceleration due to gravity
When truck moves maximum force will be equal to
It is given that half of the weight is supported by its drive wheels
So force required
From newtons law maximum acceleration will be equal to
Acceleration= change in velocity/time; 5/2.8 , so a=1.785714286
Answer: Things continue doing what they are doing unless a force is applied to it. Objects have a natural tendency to resist change. This is INERTIA. Heavier objects (objects with more mass) are more difficult to move and stop. Heavier objects (greater mass) resist change more than lighter objects, so true
Explanation:
Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop. The Cadillac has more of a tendency to stay stationary (or continue moving), and resist a change in motion than a bicycle.
