Two people pull as hard as they can on horizontal ropes attached to a boat that has a mass of 200 kg. If they pull in the same direction, the boat has an acceleration of 1.42 m/s2 to the right. If they pull in opposite directions, the boat has an acceleration of 0.509 m/s2 to the left. What is the magnitude of the force each person exerts on the boat

192.9N and 91.1N

Explanation:

Let the force exerted by one person = X

Let the force exerted by the other person = y

Then, we can create equations

When both persons pull in the same direction, then

X + Y = 200 * 1.42

When both persons pull I'm opposite directions, then

X - Y = 200 * 0.509

Now we have

X + Y = 284

X - Y = 101.8

When we add the 2 equations together, we get

2X = 385.8

X = 385.8/2

X = 192.9

If x = 192.9, then, y = 284 - x

Y = 91.1

Therefore, one person exerts 192.9N, and the other exerts 91.1N

answer: (431,2)

step-by-step explanation:

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.
