The weight of a 75 kg person on Earth, which has an acceleration due to gravity of 9.8m/s², is 735N.
CALCULATE WEIGHT:
Weight is a force, hence, measured in Newton. It is a function of an object's mass in relation to gravity.
Weight of an object can be calculated using the following formula:
W = mg
Where;
- W = weight (N)
- m = mass (kg)
- g = acceleration due to gravity (m/s²)
The weight of the person in this question can be calculated as follows:
W = 75 × 9.8
W = 735N
Therefore, the weight of a 75 kg person on Earth, which has an acceleration due to gravity of 9.8m/s², is 735N.

Answer:
(a). The spring compressed is 
.
(b). The acceleration is 1.5 g.
Explanation:
Given that,
Acceleration = a
mass = m
spring constant = k
(a). We need to calculate the spring compressed
Using balance equation
....(I)
The spring compressed is .
(b). If the compression is 2.5 times larger than it is when the mass sits in a still elevator,
The compression is given by
Here, acceleration is zero
So, 
We need to calculate the acceleration
Put the value of x in equation (I)
Hence, (a). The spring compressed is .
(b). The acceleration is 1.5 g.
