Consider a bus traveling to the west (negative x direction) that begins to slow down as it approaches a traffic light. Which statement concerning its acceleration in the x direction is correct

Complete question is;

Consider a bus traveling to the west (-x direction) begins to slow down as it approaches a traffic light. Which statement concerning its acceleration in the x direction is correct

a) The bus is decelerating and its acceleration is positive.

b) The bus is decelerating, and its acceleration is negative.

c) The acceleration is zero.

d) A statement cannot be made using the information given.

Option A - bus is decelerating and acceleration is positive.

Explanation:

We are told that the bus is travelling in (negative x direction) and begins to slow down. Since the bus is slowing down, it means that the bus is undergoing a negative acceleration which is called deceleration.

Thus, the bus is decelerating.

Since it is moving in the negative x-axis, it means acceleration is now; -(-a) which gives +a.

Thus, bus is decelerating and acceleration is positive.

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.
