What is the acceleration of a bus that goes from rest to a speed of 50km/h in 10s?

Acceleration of the bus is 1.38 m/s^2

Explanation:

Given that,

Initial speed of the bus, u = 0 m/s (rest)

Final speed of the bus, v = 50 km/h

or v = 13.88 m/s

Time taken, t = 10 s

To find :

The magnitude of the acceleration of the car.

Solve :

Let a is the acceleration of the car. The rate of change of velocity is called the acceleration of the bus. Its formula is given by :

Therefore, the magnitude of the car's acceleration is 1.38 m/s^2.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
