Triple the dimensions, multiply, and you get D
Answer:
a=2, b = 1, m=9
Step-by-step explanation:
i. 7 = 2a+3 -----> 4=2a---------> a=2
ii. -1 = 2b-3 -------> 2 = 2b ------> b = 1
iii. 2(3)+3 = m -------> 6+3 = m -------> m=9
Hope this helps!!! :D
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
