Answer:
D
Explanation:
cuz it transforms from one to another can't be created not destroyed.PERIOD!
Upward and downward forces cancel out. Net force is 8 newtons to the right
Answer:
Important enough for someone to ask you to do it.
Explanation:
If someone asked you this question, then it must be important and stuff. This is proven by scientific stuff that no one cares about.
Answer : 413.44N
Here it is given that an elevator is moving down with an acceleration of 3.36 m/s² . And we are interested in finding out the apparent weight of a 64.2 kg man . For the diagram refer to the attachment .
- From the elevator's frame ( non inertial frame of reference) , we would have to think of a pseudo force.
- The direction of this force is opposite to the direction of acceleration the frame and its magnitude is equal to the product of mass of the concerned body with the acceleration of the frame .
- When a elevator accelerates down , the weight recorded is less than the actual weight .
From the Free body diagram ,
- Mass of the man = 64.2 kg
