Using the free body diagram above for a 1-kg box being pushed across a level floor, describe the change in motion for the box when the applied force is 10N and the frictional force is 8 N.
A)
The box will decelerate at a rate of 8 m/s?
B)
The box will accelerate at a rate of 8 m/s2
The box will decelerate at a rate of 2 m/s?
D
The box will accelerate at a rate of 2 m/s?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

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.

find the sum of the two horizontal vectors and the sum of the two vertical vectors

its a circle not a square that's simple silly.
