- initial velocity=u=24m/s
- Acceleration=a=4m/s^2
- Distance=s=96m
- Final velocity=v
Using 3rd equation of kinematics







Answer:
That is not true all objects fall at the same speed excepts things like feathers or paper.
Answer:
Im gonna say it is answer A:) Hope this helps!
Explanation:
Answer:
<h2>80,000 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
PE = 250 × 10 × 32
We have the final answer as
<h3>80,000 J</h3>
Hope this helps you
Answer:

Explanation:

Determine the speed of the jet
The speed is calculated as:

Substitute 4800 km for Distance and 6hr for Time


<em>Hence, the speed of the commercial jet is 800km/hr</em>
