The total momentum of a system is the vector sum of all the individual masses that comprise the system.
Moreover, To calculate the total momentum of two objects during a collision, add their individual momentums. You can calculate the momentum for each object using the formula p=mv, where p is the momentum, m is the mass, and v is the velocity. The law of conservation of momentum can be expressed as follows. For a collision between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

The required work to hold the crate above the ground is 150 joule.
We need to know about the work done to solve this problem. The work done by an object depends on the force applied and the distance. The work is proportional to force and displacement. It can be written as
W = F . s
where W is work done, F is the force and s is displacement
From the question above, the given parameters are
F = 100 N
s = 1.5
Thus, the required work to hold the crate above the ground can be calculated
W = F . s
W = 100 . 1.5
W = 150 joule
