Answer:
Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass.
If the mass increases, it's harder to accelerate
They both have exactly the same acceleration.
Answer:
A) 19.994 m B) 1.750 seconds
Explanation:
We are asked about time and height at which both balls pass at the same height. So both, <em>TIME </em>and <em>HEIGHT</em> of both vertical trajectories are the same.
To find the values we use the kinematics expression for vertical motion with constant acceleration, using as the gravity acceleration -9.8 m/s2. Motion downwards is negative and upwards is positive. The reference point is the bottom of the building. The equation is as follow:
For each ball this equation is:
Since the data of the problem is using SI units, then our answers will be expressed in SI units as well. Now, we first compute part B by equaling both equations (same height) and solving for time:
With this time we can find the Height by substituting it in any equation of the balls. In this case, we use the expression of ball B
Answer:engineers come up with scientific questions when they are developing their design, and scientists do research to answer them.
