70-kg man standing on a scale in an elevator notes that as the elevator rises, the scale reads 844 N. What is the acceleration of the elevator?

Answer : The acceleration of the elevator is,

Explanation :

Formula used to calculate the acceleration of the elevator is:

where,

F = force = 844 M

m = mass of man = 70 kg

g = acceleration due to gravity =

a = acceleration of the elevator = ?

Now put all the given values in the above formula, we get:

Thus, the acceleration of the elevator is,
