A box sliding down a hill going 3m/s accelerates at 2m/s2. How fast is going 4 seconds?

11 m/s

Explanation:

The motion of the box is a uniformly accelerated motion (=constant acceleration), therefore we can use the following suvat equation:

where:

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time

For the box in this problem, we have:

u = 3 m/s is the initial velocity

is the acceleration

t = 4 s is the time interval

Solving for v, we find the velocity after 4 seconds:

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

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.
