Question

On earth, a block is placed on a frictionless table. When a 50 N horizontal force is applied to the block, it accelerates at 4.0 m/s2. Suppose the block and table are set up on the moon. When a horizontal force of 25 N is applied to the block, what is the acceleration?

Answer 1

Explanation:

As per Newton's II law we know that

here

F = applied unbalanced force

m = mass of object

a = acceleration of object

now it is given that force F = 50 N North applied on block on earth due to which block will accelerate by 4 m/s^2

so here from above equation

Now we took another situation where block is placed on surface of moon and again force F = 25 N is applied on the block

So we will again use Newton's II law

so block will accelerate on moon by acceleration 2 m/s^2
