To develop this problem we will begin to determine the distances traveled in each of the segments using the linear motion kinematic equations. For this purpose, the distance traveled will be determined by the product between speed and time.
Part A is attached and indicates the graph of distance traveled vs time. And the calculations for development are found below. With the distance traveled and the total time it will be possible to find the average speed of the second part.
In 1.5 min the distance covered was,
In the next 3.5min the distance covered is 0.
The distance covered for the next 2.5 min is
Total distance covered is
For the average distance we need to use the total distance covered in the total time used. Then,
The time of motion of the ball from the vertical height is independent of the horizontal velocity.
Horizontal moving projectiles is not affected by gravity and the initial velocity is equal to the final velocity.
The time of motion of ball dropped from a vertical height is calculated as follows;
where;
- <em>h </em><em>is the vertical height</em>
- <em>t </em><em>is the </em><em>time </em><em>of motion</em>
- <em>g </em><em>is acceleration due to gravity</em>
- <em />
<em> is the initial </em><em>vertical velocity</em>
From the equation above, we can conclude that time of motion of the ball from the vertical height is independent of the horizontal velocity.
If there is variation in drop time, it could be as a result of applied force when the ball is dropped. This applied force influences the initial velocity which in turn alters the drop time.
Generally, horizontal moving projectiles is not affected by gravity and the initial velocity is equal to the final velocity.

Answer:
Explanation:
acceleration is the time rate of change of velocity
a = (51 - 20) / 3 = 10⅓ mi/hr/s
which should probably be converted to standard units.
10⅓ mi/hr/s(5280 ft/mi) / 3600 s/hr) = 15.15555... ≈ 15.2 ft/s²
which is roughly half the acceleration of gravity.
Answer:
Explanation:
Energy and mass are related by the famous equation developed by Albert Einstein:
where m = mass and c = speed of light
This equation explains that an object with very small mass can produce a large amount of energy in reactions such as a nuclear reaction.
Hence, the energy produced by the explosion of a Plutonium bomb containing 3.6 grams of matter is:
E =
Answer:
Lower
Lower
gsintheta (gsinθ)
Explanation:
The sum of forces resolved parallel to the inclined plane is given by;
F - mgsinθ = 0
ma - mgsinθ = 0
ma = mgsinθ
a = gsinθ
Acceleration is proportional to angle of inclination, thus the lower the angle of the slope, lower the acceleration along the ramp.
therefore, the speed at the bottom of a slope will be lower, (velocity is directly proportional to acceleration) and, consequently, the control will be better.
The acceleration along the ramp, is gsintheta (gsinθ)
