In the figure below a box of mass m = 0.19kg compresses a spring with spring constant k = 200 N/m by an amount x = 0.15 m. The box is initially at rest. The box is then released. After the box leaves the spring, the box goes through a region in the ground of length d = 0.85 m where friction acts on the box with a kinetic friction coefficient μk = 0.27. After leaving this region of length d, there is no more friction. The box comes to rest after it reaches a height h above the ground. The acceleration due to gravity is g = 9.8 m/sec2, as usual. What is h?

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
