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.

Answer:

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.

How long would it take for a resultant upward force of 100 N to increase the speed of 50 Kg object from 100 m/s to 150 m/s ?
Wewaii [24]

Answer:

force = mass \times acceleration \\ 100 = 50 \times a \\ a = 2 \:  {ms}^{ - 2}  \\ from :  \:  \: v = u + at \\ 150 = 100 + (2 \times t) \\ 50 = 2t \\ time = 25 \: seconds

2.2 kg box is being dragged to right with 31.06 N force and accelerating at 3.2 m/s^2 how strong is force of friction acting on
insens350 [35]

24. 02 N force of friction acting on the box.

<h3 /><h3>What is force?</h3>

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Force = mass. acceleration

Force = (2.2).(3.2)

Force = 7.04 N

Total force applied is 31.06 N

Frictional force = 31.06 - 7.04

Frictional force = 24. 02 N

24. 02 N force of friction acting on the box.
