Answer:
F = 32 [N]
Explanation:
To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
F = forces applied [N] (units of Newtons)
m = mass = 40 [kg]
a = acceleration = 0.8 [m/s²]
Now replacing:
gravitational force is the attraction force of earth on an object which is near the surface of earth
It will not depend on the velocity or acceleration of earth
So it will not change while an object is stationary or it is moving with some acceleration
So here we will say that force will remain the same
