Answer:
The magnitude is "3.8 m/s²", in the upward direction.
Explanation:
The given values are:
Mass,
m = 88 kg
Scale reads,
T = 900 N
As we know,
⇒ [tex]N=mg[/tex]
On substituting the given values, we get
⇒ [tex]=88\times 9.8[/tex]
⇒ [tex]=862.4 \ N[/tex]
Now,
⇒ [tex]T=mg-ma[/tex]
On substituting the given values in the above equation, we get
⇒ [tex]900=862.4-9.8 a[/tex]
On subtracting "862.4" from both sides, we get
⇒ [tex]900-862.4=862.4-9.8 a-862.4[/tex]
⇒ [tex]37.6=-9.8a[/tex]
⇒ [tex]a=-\frac{37.6}{9.8}[/tex]
⇒ [tex]a=3.8 \ m/s^2[/tex] (upward direction)
