The reaction force exerted by the floor of the elevator on the man is D.944 N
Step-by-step explanation:
When the elevator is accelerating upwards at 2 m/s² there occurs a fictitious force acting downwards to produce a downward acceleration of 2 m/s².
The formula to apply here is ;
Weight due to gravity=mg where m is mass of the man and g is acceleration due to gravity.
Due to additional downward acceleration the total acceleration downwards will be : 9.8+2 = 11.8 m/s²
The man weighs down on the elevator floor with a force of ;
F=m(a+g) where m is mass of man, a is acceleration
F=80( 9.8+2)
F=80(11.8)= 944 N
The reaction force by the floor of the elevator is thus 944 N

The answer is 3 and you have to subsitute -6 in for n to get your answer
.33 in its simplest form is 1/3 I think
8 * 63 = 8 * ? + 8 * 3 = ?
Okay, so we have 8 * 63, and it is broken down to 8 * ? + 8 * 3.
63 - 3 = 60, so our number should be 60.
8 * 63 = 8 * 60 + 8 * 3 = ?
To find the last number, we can just multiply 8 * 63, which is 504.
8 * 63 = 8 * 60 + 8 * 3 = 504
