Final answer:
The weight of the student on the planet Mercury would be approximately 462.5 Newtons.
Step-by-step explanation:
The weight of an object can be calculated using the formula:
Weight = mass x gravity
On the planet Mercury, the acceleration due to gravity is approximately 3.7 m/s². Since the mass of the student is given as 125 kg, we can calculate the weight:
Weight = 125 kg x 3.7 m/s² = 462.5 N
Therefore, the student would weigh approximately 462.5 Newtons on the planet Mercury.
