1 answer:
The force applied by the student is 75 N
Explanation:
We can solve this problem by using Newton's second law, which states that the force applied on an object is equal to the product between the mass of the object and its acceleration:
where
F is the force applied
m is the mass of the object
a is the acceleration
In this problem,
m = 50 kg
Substituting, we find the force applied by the student:
