Answer:
Explanation:
Step one:
given data
mass = 7kg
acceleration =2m/s^2
time= 9seconds
acceleration = velocity/time
velocity= acceleration *time
velocity=2*9
velocity= 18m/s
distance moved= velocity* time
distance= 18*9
distance=162m
we also know that the force on impulse is given as
Ft=mv
F=mv/t
F=7*18/9
F=126/9
F=14N
work done = Force* distance
work done=14*162
work=2268Joules
work= 2.27kJ
The answer is 2.66 x 10^8 J.
It's A.Gas molecules moving more quickly..... hope it helps you dear
The motion diagram for A-E is attached.
F) The drawings will change to reflect how the spacings of the respective positions are changing more irregularly.
<h3>What are motion diagrams?</h3>
A motion diagram is an image that represents the position of an object at various relatively spaced time intervals.
The art of using motion diagrams is called kinematics. it is useful for detecting the unknown speed of objects. For example, the movement of a rocket from earth to space, the movement of a ship over the water.
