Answer:
The block has an acceleration of
Explanation:
By means of Newton's second law it can be determine the acceleration of the block.
(1)
Where represents the net force, m is the mass and a is the acceleration.
(2)
The forces present in x are and
(the friction force):
Notice that subtracts to
since it is at the opposite direction.
The forces present in y balance each other:
Therefore:
(3)
But and writing (3) in terms of a it is get:
So the block has an acceleration of .
In projectile motion we know that range of projectile is given as
also the maximum height is given as
so here we can see that maximum height and range on earth will inversely depends on gravity
now if we compare this height and range on earth and moon
similarly for height we have
so both will increase by factor of 7.26
